Filling opioid prescriptions akin to a Sisyphean task
Pain management is a huge part of how we in palliative care help patients – and most of the time, I think we do it well, but in the regulatory environment of the opioid epidemic,
A patient – let’s call her Joan – calls me in distress. She is a 62-year-old woman with widespread metastatic breast cancer. Her pain is mainly due to bone metastases, but she also has discomfort due to the cancer’s invasion of the thin membranes that line her lungs and abdomen.
She was started on a combination opioid and acetaminophen tablet about 2 months ago by her oncologist, but is now requiring it around the clock, nearing the ceiling dose for this particular medication.
Given that her pain is escalating, Joan and I discuss starting a long-acting opioid to better manage the peak and trough effect of short-acting opioids, which can make a patient feel that the pain is relieved only for a few hours at a time, with sharp spikes throughout the day that mandate the next dose of short-acting opioid. This tethers the patient to the clock, having to take as many as six or eight doses of medication per day, and can be very disruptive to daily life.
I send an e-prescription for the same opioid Joan’s currently taking, but in a long-acting format that will slow-release over 8-10 hours, relieving her of the need to take a medication every 3-4 hours. I have learned over the years that nearly every long-acting opioid automatically generates a prior authorization request from the patient’s insurance company and so I immediately email our prior authorization team to submit to Joan’s insurance right away to avoid this extra delay.
Our prior authorization team is exceptionally responsive and submits these requests with urgency every time – they understand that cancer pain is a serious problem and we can’t wait 5 business days for answers. They are typically able to obtain an approved prior authorization for nearly every long-acting opioid I write within 24-48 hours.
But here’s where things go sideways.
First, the insurance company denies the prior authorization request, demanding that I revise the prescription from the long-acting version of the opioid she is currently taking to a cheaper, older opioid that she’s never tried before. In other words, they won’t cover the drug I requested without Joan first trying a completely different drug and failing it. This only makes sense for the insurance company’s bottom line – it makes no clinical sense at all. Why would I try a novel compound that Joan’s never had and one to which I have no idea how she’ll respond when I could keep her on the same compound knowing that she tolerates it just fine?
Past experience tells me insurance companies rarely budge on this, and appealing the decision would just introduce even more delay of care, so I begrudgingly change the prescription and send it again to the pharmacy. I message Joan to let her know that her insurance won’t cover my drug of choice and that we have to try this older one first.
A few hours later, Joan sends me a message: “My pharmacy says it’s going to take A WEEK to get the long-acting medicine!”
In the meantime, Joan has been using her short-acting opioid faster than anticipated because of her escalating pain – so she’s now running low on that as well.
I write for more of her short-acting opioid and e-script it to her pharmacy.
Within a few hours, we get another automatic response from her insurance that we’re going to need a prior authorization for additional short-acting opioid because she’s exceeded “quantity limitations,” which as far as I can tell is a completely arbitrary number not based on clinical evidence.
The prior auth team jumps on it and submits to override the quantity limit – successfully – and sends the override code to her pharmacy to reprocess the prescription.
But now the pharmacist tells Joan that they won’t fill the Rx anyway because it’s “too early.” They tell her that “state laws” prevent them from filling the scrip.
Is this true? I have no idea. I’m not an expert on California pharmacy law. All I know is that my patient is in pain and something needs to happen quickly.
I write for a second short-acting opioid – again a completely different compound. Ironically, this Rx goes through instantly without need for prior authorization. But now Joan has to switch to another new drug for no good medical reason.
If you’re still with me this far into the weeds, I’m grateful. In all it took a combined 4 hours of work (between myself and the prior auth team) to get two opioid Rx’s filled – and these were completely different medications than the ones I originally wrote for. I also had to move her prescriptions to the hospital’s pharmacy (another inconvenience for Joan and her family) so that she could get the medications in a timely manner. All this work to ensure that a single patient had adequate and timely pain relief and to prevent her from having to make an unnecessary visit to the emergency department for pain crisis.
This is just a regular day in outpatient palliative care in the era of the opioid epidemic.
The epidemic has caused tremendous pain and suffering for millions of people over the past 2 decades – namely those lost to opioid overdoses and their loved ones. And for the most part, tightening access to opioids for routine aches and pains among a relatively healthy population is not wrong, in my opinion, as long as those restrictions are based in good faith on robust evidence.
But the hidden cost of the Centers for Disease Control and Prevention’s 2016 opioid prescribing guidelines for nonmalignant pain, as well as the flurry of restrictive state laws they generated, is felt every day by patients with serious illness even though the guidelines were never meant to affect them. Patients with active cancer, receiving palliative care services, or at the end of life, were supposed to be exempted from these guidelines since good evidence supports the use of opioids in these populations.
Instead of preserving access to desperately needed pain medicine for those suffering with serious illness, states and insurers have aggressively sought to gatekeep opioids from everyone, resulting in stigma, delays, and needless suffering.
Several recent studies have revealed the effects of this gatekeeping on patients with cancer.
A qualitative study with 26 advanced cancer patients described the demoralization and stigma many patients felt when taking opioids, which they directly tied to media messaging around the opioid epidemic. Even when they reluctantly agreed to take opioids to treat cancer-related pain, there were systemic impediments to achieving adequate pain relief – similar to my experience with Joan – that were directly caused by insurance and pharmacy constraints.
Those of us who care for oncology patients also appear to be undertreating cancer-related pain. Another recent study that found the amount of opioid medications prescribed to an advanced cancer patient near the end of life dropped by 38% between 2007 and 2017. The authors suggest that a direct consequence of this decline in appropriate opioid prescribing is an observed 50% rise in emergency department visits over the same time period by cancer patients for pain-related reasons.
This makes sense – if patients aren’t routinely prescribed the opioids they need to manage their cancer-related pain; or, if the stigma against using opioids is so harsh that it causes patients to shun opioids; or, if there are so many system barriers in place to prevent patients from obtaining opioids in a timely manner – then patients’ pain will crescendo, leaving them with little alternative but to head to the emergency department.
This undertreatment is corroborated by another study that examined data from the Centers for Medicare & Medicaid Services Part D prescriber database between 2013 and 2017, finding that both oncologists and nononcologists prescribed about 21% fewer opioids to Medicare beneficiaries during that time, compared with the period prior to 2013.
Interestingly, the researchers also found that opioid prescribing by palliative care providers increased by 15% over the same period. On a positive note, this suggests the presence of a growing outpatient palliative care workforce. But it may also reflect growing unease among oncologists with the perceived liability for prescribing opioids and a desire to ask other specialists to take on this liability. At the same time, it may reflect the very real and ever-increasing administrative burden associated with prescribing opioids and the fact that busy oncologists may not have time to spend on this aspect of cancer care. Thus, as palliative care clinicians become more visible and numerous in the outpatient arena, oncologists may increasingly ask palliative care clinicians like myself to take this on.
The problem with this is that merely handing off the administrative burden to another clinician doesn’t address the underlying problem. Anecdotal evidence suggests (and my own experiences corroborate) this administrative burden can cause real harm. A survey of 1,000 physicians conducted by the American Medical Association in 2021 found that 93% of respondents reported a delay in patient care due to prior authorization burden and 34% of respondents reported that their patients had suffered a “serious adverse event” due to prior authorization requirements.
The CDC recently announced it will take steps to revise the 2016 opioid prescribing guidelines for chronic pain after hearing from members of the medical community as well as patients living with chronic pain about the harsh, unintended consequences of the guidelines. I can only hope that insurance companies will follow suit, revising their opioid prior authorization requirements to finally come into alignment with the rational, safe use of opioids in patients with advanced cancer. It’s too bad that any improvement in the future will be too late for the millions of patients who have suffered irreversible iatrogenic harms due to delays in achieving adequate pain relief.

Study questions reliability of maternal drug testing
A new study finding that samples from maternal urine and the meconium of their newborn babies frequently produce different results is raising more questions about drug testing of pregnant women.
The study found concerningly high rates of disagreement (or “discordance”) in biochemical testing between maternal urine in women with a documented history of or active drug use and the meconium in their newborns. In some cases, such discordance might be triggering the inappropriate intervention of childcare protective services, including the separation of infants from their mothers, according to the researchers, who presented their findings Feb. 4 at the meeting sponsored by the Society for Maternal-Fetal Medicine.
“There’s a very big debate right now in the obstetrics and perinatology communities about the utility of biochemical testing and the identification of high-risk women,” lead author Cassandra Heiselman, DO, MPH, clinical assistant professor in the department of obstetrics, gynecology and reproductive medicine at Stony Brook (N.Y.) University, said in an interview. “We know that each biochemical test has limitations, which can include basically the inability to detect all substances, especially synthetic opioids like fentanyl, [and] the possibility for false results.”
Inaccuracies in testing can potentially result in inappropriate separation of mother and baby. “Careful scrutiny of results is needed,” Dr. Heiselman said.
The Stony Brook team conducted a retrospective cohort study that identified women presenting for delivery from January 2017 to March 2021 with indications for drug testing, including a known history of or current substance use disorder/misuse, and late or no prenatal care. A standardized panel was used for testing maternal urine and newborn meconium.
Urine tests of 327 women resulted in 187 (57%) positive and 98 (30%) negative results, along with 42 (13%) samples with incomplete data, the researchers reported. In contrast, drug testing of newborn meconium was positive in 273 (83%) cases, negative in 42 (13%), and was not performed in 12 (4%) – for a rate of concordance of 41%.
Concordance of urine/meconium occurred more frequently in male newborns (65%), compared with females (35%). “It is unclear biologically why there is such a difference based on the sex of the infants’ test and is an area that needs further investigation,” Dr. Heiselman said.
Comparing urine and meconium tests for 11 substances resulted in 195/483 (40%) concordance, the researchers said; 18% were discordant with positive maternal urine, and 41% were discordant with newborn positive meconium.
Oxycodone and fentanyl were significantly discordant with positive maternal urine. Cannabis use was the most common factor associated with a positive test of meconium, according to the researchers.
“Some studies have shown cannabis use in the second trimester can show up in meconium testing even if the mother has stopped that behavior,” Dr. Heiselman said. “Then there is also cross-reactivity with other substances that can lead to higher false positive results, especially in the urine toxicology.”
The reasons for the discordant results are not clear and vary by substance, Dr. Heiselman said.
“Cannabis and methadone were the significant factors leading to discordance with positive newborn meconium, which may reflect prior use earlier in pregnancy without recent use before delivery,” she said in an interview. “Urine and meconium reflect potentially different timing in perinatal exposure and the potential differences in windows of detection for different substances. Therefore, we would expect some discordance in our comparisons, just not the extent that we saw.”
Some test results might also have been false positives. Many commonly used medications, from cough syrups to proton pump inhibitors, have the potential to generate positive results for illicit drugs, Dr. Heiselman said.
“The issue of discordance is a complex one, where there are limitations of the tests being performed, possible cross-reactivity with false positives, and the difference in what test reflects as far as timing of prenatal exposure. Furthermore, a negative test does not rule out sporadic use, nor does a positive result diagnose substance use disorder or its severity,” she said.
Lack of standards
Dr. Heiselman said states and the federal government lack standards to biochemically evaluate women at risk for drug abuse and their newborns.
“My institution uses a risk-based protocol. Basically, we test cases where we have a known history of substance use disorder or active use, a history in the last 3 years of any kind of substance use, initiation of late prenatal care after 20 weeks, or no prenatal care at all,” she said. “And then the pediatricians on the other side will test neonates if the mother has any of that history or if the neonates themselves have unexplained complications or drug withdrawal symptoms.”
High rates of discordance can result in the inappropriate intervention by childcare protective service agencies when the mother may not have a substance use disorder, she noted.
Perinatologist Kecia Gaither, MD, MPH, associate professor of clinical obstetrics and gynecology at Weill Cornell Medicine, New York, called the findings “no surprise,” but added that negative findings in neonates “do not exclude the possibility of substance abuse by the mother. It is important to recognize the limitations inherent with screening tests for illicit substances in neonates from substance-abusing mothers.”
Dr. Heiselman added that understanding what maternal and infant drug tests truly reflect “can help us as clinicians in deciding when we test, whether it’s medically necessary, instead of just thinking biochemical tests are the best screening tool, because we know that we are screening. We must engage these women in empathetic and nonjudgmental discussions, which often will elucidate a substance use disorder history more so than just biochemical testing, negative or positive.”
The researchers disclosed no relevant financial relationships.

Concordance of urine/meconium occurred more frequently in male newborns (65%), compared with females (35%). “It is unclear biologically why there is such a difference based on the sex of the infants’ test and is an area that needs further investigation,” Dr. Heiselman said.
Comparing urine and meconium tests for 11 substances resulted in 195/483 (40%) concordance, the researchers said; 18% were discordant with positive maternal urine, and 41% were discordant with newborn positive meconium.
Oxycodone and fentanyl were significantly discordant with positive maternal urine. Cannabis use was the most common factor associated with a positive test of meconium, according to the researchers.
“Some studies have shown cannabis use in the second trimester can show up in meconium testing even if the mother has stopped that behavior,” Dr. Heiselman said. “Then there is also cross-reactivity with other substances that can lead to higher false positive results, especially in the urine toxicology.”
The reasons for the discordant results are not clear and vary by substance, Dr. Heiselman said.
“Cannabis and methadone were the significant factors leading to discordance with positive newborn meconium, which may reflect prior use earlier in pregnancy without recent use before delivery,” she said in an interview. “Urine and meconium reflect potentially different timing in perinatal exposure and the potential differences in windows of detection for different substances. Therefore, we would expect some discordance in our comparisons, just not the extent that we saw.”
Some test results might also have been false positives. Many commonly used medications, from cough syrups to proton pump inhibitors, have the potential to generate positive results for illicit drugs, Dr. Heiselman said.
“The issue of discordance is a complex one, where there are limitations of the tests being performed, possible cross-reactivity with false positives, and the difference in what test reflects as far as timing of prenatal exposure. Furthermore, a negative test does not rule out sporadic use, nor does a positive result diagnose substance use disorder or its severity,” she said.
Lack of standards
Dr. Heiselman said states and the federal government lack standards to biochemically evaluate women at risk for drug abuse and their newborns.
“My institution uses a risk-based protocol. Basically, we test cases where we have a known history of substance use disorder or active use, a history in the last 3 years of any kind of substance use, initiation of late prenatal care after 20 weeks, or no prenatal care at all,” she said. “And then the pediatricians on the other side will test neonates if the mother has any of that history or if the neonates themselves have unexplained complications or drug withdrawal symptoms.”
High rates of discordance can result in the inappropriate intervention by childcare protective service agencies when the mother may not have a substance use disorder, she noted.
Perinatologist Kecia Gaither, MD, MPH, associate professor of clinical obstetrics and gynecology at Weill Cornell Medicine, New York, called the findings “no surprise,” but added that negative findings in neonates “do not exclude the possibility of substance abuse by the mother. It is important to recognize the limitations inherent with screening tests for illicit substances in neonates from substance-abusing mothers.”
Dr. Heiselman added that understanding what maternal and infant drug tests truly reflect “can help us as clinicians in deciding when we test, whether it’s medically necessary, instead of just thinking biochemical tests are the best screening tool, because we know that we are screening. We must engage these women in empathetic and nonjudgmental discussions, which often will elucidate a substance use disorder history more so than just biochemical testing, negative or positive.”
The researchers disclosed no relevant financial relationships.

A new study finding that samples from maternal urine and the meconium of their newborn babies frequently produce different results is raising more questions about drug testing of pregnant women.
The study found concerningly high rates of disagreement (or “discordance”) in biochemical testing between maternal urine in women with a documented history of or active drug use and the meconium in their newborns. In some cases, such discordance might be triggering the inappropriate intervention of childcare protective services, including the separation of infants from their mothers, according to the researchers, who presented their findings Feb. 4 at the meeting sponsored by the Society for Maternal-Fetal Medicine.
“There’s a very big debate right now in the obstetrics and perinatology communities about the utility of biochemical testing and the identification of high-risk women,” lead author Cassandra Heiselman, DO, MPH, clinical assistant professor in the department of obstetrics, gynecology and reproductive medicine at Stony Brook (N.Y.) University, said in an interview. “We know that each biochemical test has limitations, which can include basically the inability to detect all substances, especially synthetic opioids like fentanyl, [and] the possibility for false results.”
Inaccuracies in testing can potentially result in inappropriate separation of mother and baby. “Careful scrutiny of results is needed,” Dr. Heiselman said.
The Stony Brook team conducted a retrospective cohort study that identified women presenting for delivery from January 2017 to March 2021 with indications for drug testing, including a known history of or current substance use disorder/misuse, and late or no prenatal care. A standardized panel was used for testing maternal urine and newborn meconium.
Urine tests of 327 women resulted in 187 (57%) positive and 98 (30%) negative results, along with 42 (13%) samples with incomplete data, the researchers reported. In contrast, drug testing of newborn meconium was positive in 273 (83%) cases, negative in 42 (13%), and was not performed in 12 (4%) – for a rate of concordance of 41%.

FROM THE PREGNANCY MEETING
Opioid exposure in early pregnancy linked to congenital anomalies
Exposure to opioid analgesics during the first trimester of pregnancy appears to increase the risk of congenital anomalies diagnosed in the first year of life, researchers report.
While the absolute risk of congenital anomalies was low, these findings add to an increasing body of evidence suggesting that prenatal exposure to opioids may confer harm to infants post partum.
“We undertook a population-based cohort study to estimate associations between opioid analgesic exposure during the first trimester and congenital anomalies using health administrative data capturing all narcotic prescriptions during pregnancy,” lead author Alexa C. Bowie, MPH, of Queen’s University in Kingston, Ont., and colleagues reported in CMAJ.
The researchers retrospectively reviewed administrative health data in a single-payer health care system from 2013 to 2018. They identified parent-infant pair records for all live births and stillbirths that occurred at more than 20 weeks’ gestation.
The exposure of interest was a prescription for any opioid analgesic with a fill date between the estimated date of conception and less than 14 weeks’ gestation. The referent group included any infant not exposed to an opioid analgesic during the index pregnancy period.
Results
The study cohort included a total of 599,579 gestational parent-infant pairs. Of these, 11,903 (2.0%) were exposed to opioid analgesics, and most were exposed during the first trimester only (75.8%).
Overall, 2.0% of these infants developed a congenital anomaly during the first year of life; the prevalence of congenital anomalies was 2.0% in unexposed infants and 2.8% in exposed infants.
Relative to unexposed infants, the researchers observed greater risks among infants who were exposed for some anomaly groups, including many specific anomalies, such as ankyloglossia (any opioid: adjusted risk ratio, 1.88; 95% confidence interval, 1.30-2.72; codeine: aRR, 2.14; 95% CI, 1.35-3.40), as well as gastrointestinal anomalies (any opioid: aRR, 1.46; 95% CI, 1.15-1.85; codeine: aRR, 1.53; 95% CI, 1.12-2.09; tramadol: aRR, 2.69; 95% CI 1.34-5.38).
After sensitivity analyses, which included exposure 4 weeks before conception or excluded individuals with exposure to opioid analgesics before pregnancy, the findings remained unchanged.
“Although the overall risk was low, we observed an increased risk of any congenital anomaly with tramadol, and a previously unreported risk with morphine,” the researchers wrote.
“Previous studies reported elevated risks of heart anomalies with first-trimester exposure to any opioid analgesic, codeine, and tramadol, but others reported no association with any opioid analgesic or codeine,” they explained.
Interpreting the results
Study author Susan Brogly, PhD, of Queen’s University said “Our population-based study confirms evidence of a small increased risk of birth defects from opioid analgesic exposure in the first trimester that was observed in a recent study of private insurance and Medicaid beneficiaries in the U.S. We further show that this small increased risk is not due to other risk factors for fetal harm in women who may take these medications.”
“An opioid prescription dispensed in the first trimester would imply that there was an acute injury or chronic condition also present in the first trimester, which may also be associated with congenital abnormalities,” commented Elisabeth Poorman, MD, MPH, a clinical instructor and primary care physician at the University of Washington in Seattle.
“Opioid use disorder is often diagnosed incorrectly; since the researchers used diagnostic billing codes to exclude individuals with opioid use disorder, some women may have been missed,” Dr. Poorman explained.
Ms. Bowie and colleagues acknowledged that a key limitation of the study was the identification of cases using diagnostic billing codes. As a result, exposure-dependent recording bias could be present and limit the applicability of the findings.
“The diagnosis and documentation of minor anomalies and those with subtle medical significance could be vulnerable to exposure-dependent recording bias,” Ms. Bowie wrote.
Dr. Poorman recommended that these results should be interpreted with caution given these and other limitations. “Overall, results from this study may imply that there is limited evidence to suspect opioids are related to congenital abnormalities due to a very small difference observed in relatively unequal groups,” she concluded.
This study received funding from the Eunice Kennedy Shriver National Institutes of Child Health and Human Development and was also supported by the Institute for Clinical Evaluative Sciences, which is funded by an annual grant from the Ontario Ministry of Health. One author reported receiving honoraria from the National Institutes of Health and a grant from the Canadian Institute of Health Research, outside the submitted work.

Two emerging drugs exacerbating opioid crisis
Two illicit drugs are contributing to a sharp rise in fentanyl-related deaths, a new study from the Centers for Disease Control and Prevention shows.
Para-fluorofentanyl, a schedule I substance often found in heroin packets and counterfeit pills, is making a comeback on the illicit drug market, Jordan Trecki, PhD, and associates reported in the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report (2022 Jan 28;71[4]:153-5). U.S. medical examiner reports and national law enforcement seizure data point to a rise in encounters of this drug along with metonitazene, a benzimidazole-opioid, in combination with fentanyl.
On their own, para-fluorofentanyl and metonitazene can kill the user through respiratory depression. Combinations of these substances and other opioids, including fentanyl-related compounds or adulterants, “pose an even greater potential harm to the patient than previously observed,” reported Dr. Trecki, a pharmacologist affiliated with the Drug Enforcement Administration, and colleagues.
Opioids contribute to about 75% of all U.S. drug overdose deaths, which rose by 28.5% during 2020-2021, according to the National Center for Health Statistics. And fentanyl is replacing heroin as the primary drug of use, said addiction specialist Brian Fuehrlein, MD, PhD, in an interview.
“For patients with stimulant use disorder and even cannabis use disorder, fentanyl is becoming more and more common as an adulterant in those substances, often resulting in inadvertent use. Hence, fentanyl and fentanyl-like drugs and fentanyl analogues are becoming increasingly common and important,” said Dr. Fuehrlein, director of the psychiatric emergency room at the VA Connecticut Healthcare System. He was not involved with the MMWR study.
Tennessee data reflect national problem
Recent data from a medical examiner in Knoxville, Tenn., illustrate what might be happening nationwide with those two emerging substances.
Over the last 2 years, the Knox County Regional Forensic Center has identified para-fluorofentanyl in the toxicology results of drug overdose victims, and metonitazene – either on its own or in combination with fentanyl and para-fluorofentanyl. Fentanyl appeared in 562 or 73% of 770 unintentional drug overdose deaths from November 2020 to August 2021. Forty-eight of these cases involved para-fluorofentanyl, and 26 involved metonitazene.
“Although the percentage of law enforcement encounters with these substances in Tennessee decreased relative to the national total percentage within this time frame, the increase in encounters both within Tennessee and nationally reflect an increased distribution of para-fluorofentanyl and metonitazene throughout the United States,” the authors reported.
How to identify substances, manage overdoses
The authors encouraged physicians, labs, and medical examiners to be on the lookout for these two substances either in the emergency department or when identifying the cause of drug overdose deaths.
They also advised that stronger opioids, such as fentanyl, para-fluorofentanyl, metonitazene, or other benzimidazoles may warrant additional doses of the opioid-reversal drug naloxone.
While he hasn’t personally seen any of these drugs in his practice, “I would assume that these are on the rise due to inexpensive cost to manufacture and potency of effect,” said Dr. Fuehrlein, also an associate professor of psychiatry at Yale University, New Haven, Conn.
The need for additional naloxone to manage acute overdoses is a key takeaway of the MMWR paper, he added. Clinicians should also educate patients about harm reduction strategies to avoid overdose death when using potentially powerful and unknown drugs. “Things like start low and go slow, buy from the same supplier, do not use opioids with alcohol or benzos, have Narcan available, do not use alone, etc.”
Dr. Fuehrlein had no disclosures.

Buprenorphine may curb opioid-induced respiratory depression
High plasma concentrations of buprenorphine may reduce fentanyl-induced respiratory depression, new research suggests.
The primary endpoint measure in a small “proof of principal” pharmacology study was effect of escalating fentanyl dosing on respiratory depression by way of decreased isohypercapnic minute ventilation (VE) – or volume of gas inhaled or exhaled per minute from the lungs.
Results showed the maximum decrease in highest-dose fentanyl-induced VE was almost 50% less for opioid-tolerant patients receiving a 2.0 ng/mL concentration of steady-state plasma buprenorphine than when receiving matching placebo.
Risk for apnea requiring stimulation after fentanyl dosing was also significantly lower with buprenorphine.
“Even though the study is small, a lot of data were collected which will allow us to very accurately predict which plasma concentrations, and therefore drug doses, are needed to protect people adequately in practice,” study coinvestigator Geert Jan Groeneveld, MD, PhD, neurologist and clinical pharmacologist at the Centre for Human Drug Research, Leiden, the Netherlands, and professor of clinical neuropharmacology at Leiden University Medical Center, told this news organization.
He added the “beautiful results” were in line with what the researchers expected and although further research is needed, the study provides a lot of useful information for clinicians.
“I think this is an approach that works, and this study makes that clear,” Dr. Groeneveld added.
The findings were published online Jan. 27, 2022, in PLoS One.
High death rate from synthetic opioids
A recent report from the Centers for Disease Control and Prevention noted that, between June 2020 and June 2021, there were more than 100,000 drug overdose deaths in the United States. Of these, more than 73,000 were attributed to opioids and more than 60,000 to synthetic opioids such as fentanyl.
Most opioid-related overdose deaths in the United States are attributable to synthetic opioids “that can unexpectedly cause respiratory depression by being ingested as a substitute for heroin or with [other] drugs,” Indivior noted in a press release.
Buprenorphine is a partial agonist that “binds with high affinity to mu-opioid receptors but displays partial respiratory depression effects,” the investigators wrote.
As reported by this news organization, the Food and Drug Administration approved buprenorphine extended release (Sublocade, Indivior) in 2017 as the first once-monthly injection for the treatment of opioid use disorder.
In the current study, which was conducted in Leiden, the Netherlands, the investigators used continuous intravenous buprenorphine in order to “mimic” the sustained plasma concentrations of the drug that can be delivered with the long-acting injectable, noted Christian Heidbreder, PhD, chief scientific officer at Indivior.
“This was an experimental medicine study, whereby we used intravenous buprenorphine to really understand the interaction with escalating doses of fentanyl” on respiratory depression, he told this news organization.
Two-part, two-period study
In part A, period one of the two-period crossover study, 14 healthy volunteers were randomly assigned to receive for 360 minutes continuous infusion of 0.02 or 0.05 mg/70 kg per hour of buprenorphine to target plasma concentrations of 0.2 or 0.5 ng/mL, respectively, or matching placebo. In the second period, participants received the alternative infusion – either placebo or the active drug.
In part B, eight opioid-tolerant patients who had used high-dose opioids for at least 3 months prior received a higher infusion rate of 0.1, 0.2, or 0.5 mg/70 kg per hour to target plasma concentrations of 1, 2, or 5 ng/mL, respectively.
The 2 ng/mL “is a very important threshold for us” and the result from several previous experiments, Dr. Heidbreder noted. So the investigators targeted that concentration as well as one below and one “much higher” in the current study.
“Because tolerance to opioid effects is poorly characterized in patients receiving long-term opioids, opioid-tolerant participants in part B had a fixed treatment sequence, receiving placebo infusion plus fentanyl challenges in period 1 to optimize the fentanyl dose escalation before buprenorphine and fentanyl were coadministered in period 2,” the investigators reported.
All participants received up to four escalating doses of intravenous fentanyl after reaching target buprenorphine plasma concentrations.
For healthy volunteers, the planned fentanyl doses were 0.075, 0.15, 0.25, and 0.35 mg/70 kg. For the opioid-tolerant patients, the doses were 0.25, 0.35, 0.5, and 0.7 mg/70 kg.
The infusions began after baseline VE had stabilized at 20 plus or minus 2 L/min, which is about four times above normal resting VE.
First clinical evidence?
Results showed fentanyl-induced adverse changes in VE were less at higher concentrations of buprenorphine plasma.
Opioid-tolerant patients receiving the 2.0 ng/mL concentration of buprenorphine had a 33.7% decrease in highest dose fentanyl-induced VE versus an 82.3% decrease when receiving placebo.
In addition, fentanyl reduced VE up to 49% (95% confidence interval, 21%-76%) in opioid-tolerant patients in all buprenorphine concentration groups combined versus reducing VE up to 100% (95% CI, 68%-132%) during placebo infusion (P = .006).
In addition, buprenorphine was associated with a lower risk versus placebo for apnea requiring verbal stimulation after fentanyl dosing (odds ratio, 0.07; P = .001).
For the healthy volunteers, the first fentanyl bolus reduced VE by 26% for those at target buprenorphine concentration of 0.5 ng/mL versus 51% when receiving placebo (P = .001). The second bolus reduced VE by 47% versus 79%, respectively (P < .001).
“Discontinuations for apnea limited treatment comparisons beyond the second fentanyl injection,” the investigators reported.
Overall, the findings “provide the first clinical evidence that high sustained plasma concentrations of buprenorphine may protect against respiratory depression induced by potent opioids,” they added.
Additional research is now “warranted to assess the competitive interaction of buprenorphine and fentanyl (as well as other illicitly manufactured fentanyl analogs) as we continue to deepen our understanding of buprenorphine as an evidence-based treatment for patients struggling with opioid use disorder,” Dr. Heidbreder said in a press release.
It’s unclear whether the study’s findings are generalizable to other populations, said Dr. Heidbreder.
“So and for that we’ll be using [the injectable] Sublocade as the medication of choice,” said Dr. Heidbreder.
“Conceptually, we feel confident about these data, but now we need to demonstrate what is happening in the real world,” he added.
The study was funded by Indivior. Dr. Groeneveld has reported no relevant financial relationships. Dr. Heidbreder is an employee of Indivior.

Orally dissolving buprenorphine tied to severe tooth decay, FDA warns
Orally dissolving medications containing buprenorphine are linked to severe dental problems, including total tooth loss, the U.S. Food and Drug Administration warns in a safety communication.
The oral side effects of these medications, which are used to treat opioid use disorder (OUD) and pain, include cavities/tooth decay, including rampant caries; dental abscesses/infection; tooth erosion; fillings falling out; and, in some cases, total tooth loss.
Multiple cases have been reported even in patients with no history of dental problems.
The FDA is adding a warning about the risk of dental problems to the prescribing information and the patient medication guide for all buprenorphine-containing medicines dissolved in the mouth.
The FDA emphasizes, however, that buprenorphine remains “an important treatment option for OUD and pain, and the benefits of these medicines clearly outweigh the risks.”
More than 300 reported cases
Buprenorphine was approved in 2002 as a sublingual tablet, and in 2015 as a film to be placed inside the cheek to treat pain. Both delivery methods have been associated with dental problems.
Since buprenorphine was approved, the FDA has identified 305 cases of dental problems associated with orally dissolving buprenorphine, including 131 classified as serious.
There may be other cases, the FDA says, as this represents only cases reported to the FDA or published in the medical literature.
, but those as young as 18 years old were also affected.
Most cases occurred in patients using the medicines for OUD; however, 28 cases of dental problems occurred in patients using it to treat pain.
In 26 cases, patients had no prior history of dental problems. Some dental problems developed as soon as 2 weeks after treatment began; the median time to diagnosis was about 2 years after starting treatment.
Among all 305 cases reported, 113 involved two or more teeth.
The most common treatment for the dental problems was tooth extraction/removal, which was reported in 71 cases. Other cases required root canals, dental surgery, and other procedures such as crowns and implants.
Recommendations
The FDA says health care providers should counsel patients that severe and extensive tooth decay, tooth loss, and tooth fracture have been reported with the use of transmucosal buprenorphine-containing medicines and emphasize the importance of visiting their dentist to closely monitor their teeth.
Patients should be counseled to continue taking buprenorphine medications as prescribed and not stop suddenly without first talking to their health care provider, as this could lead to serious consequences, including relapse, misuse or abuse of other opioids, overdose, and death.
Patients are also being advised to take extra steps to help lessen the risk of serious dental problems.
Patients should also be educated on strategies to maintain or improve oral health while taking transmucosal buprenorphine medicines.
Counsel them that after the medicine is completely dissolved, the patient should take a large sip of water, swish it gently around the teeth and gums, swallow, and wait at least 1 hour before brushing their teeth, as the FDA advises. This will allow time for the mouth to gradually return to oral homeostasis and avoid any mechanical damage that may occur due to brushing.
The FDA also advises that patients tell their provider about any history of tooth problems, including cavities, and schedule a dentist visit soon after starting the medicine.
Dental problems related to transmucosal buprenorphine-containing medicines should be reported to the FDA’s MedWatch program.

Opioid agonist therapy guards against self-harm, suicide
FROM THE LANCET PSYCHIATRY
Cessation of opioid agonist therapy (OAT) significantly increases the risk of self-harm and death by suicide in the first month after stopping the treatment in new findings that highlight the need for “advanced safety planning” during this critical time.
Investigators found that 4 weeks after stopping OAT, the risk of death by suicide was almost five times higher and the risk of hospital admission for self-harm was almost three times higher during this period, compared with the 4 weeks after initiation of OAT to treatment end.
These results highlight the importance of a “transition” period when stopping OAT and highlight the need for better supports for patients coming off this treatment, study investigator Prianka Padmanathan, MD, PhD candidate, Population Health Sciences, University of Bristol (England), told this news organization.
She noted the study supports previous findings that OAT “has an important role” in suicide prevention.
“Suicide and self-harm risk is greatly increased during treatment cessation, and advanced safety planning and additional psychosocial support during this time may be required,” Dr. Padmanathan said.
The findings were published online Dec. 15 in The Lancet Psychiatry.
Suicide, self-harm risk
Previous research shows an increased risk for overdose deaths and death in general during the first few weeks of starting and stopping treatment for opioid dependence.
“We wanted to see if the risk of dying by suicide was also elevated during these times,” said Dr. Padmanathan. As suicides are relatively rare, the researchers also looked at self-harm, “which is an important risk factor for suicide.”
, particularly buprenorphine or methadone.
“We tried to exclude people prescribed these drugs for pain and focused specifically on their prescription for opioid dependence,” Dr. Padmanathan said.
They estimated rates and adjusted risk ratios of hospital admissions for nonfatal self-harm and completed suicide during treatment initiation, maintenance, and cessation.
The study included 8,070 patients (69.3% men; mean baseline age, 33.3 years) who received OAT at least once from January 1998 through November 2018. The median treatment time was 84 days. Most of the participants lived in the most deprived neighborhoods and were White.
There were 807 hospital admissions for self-harm (1.99 per 100 person-years) and 46 suicides (0.11 per 100 person-years).
The investigators examined age, sex, socioeconomic status, number of previous OAT treatment episodes, previous self-harm, previous mental illness, and major chronic illness scores as potential confounders.
Need for psychosocial care
Results showed the risk for self-harm was significantly increased while off OAT (aRR, 1.5; 95% confidence interval, 1.21-1.88).
The overall age- and sex-standardized mortality ratio for suicide was 7.5 times higher (95% CI, 5.5-10) in the study cohort, compared with the general population in England between 1998 and 2017.
There was insufficient evidence to show the risk for suicide was higher off, versus on, treatment, but this may be because suicides are relatively rare, Dr. Padmanathan noted.
“The sample may have been too small to enable a difference to be detected. In contrast, self-harm is more common, so there was power to detect a difference there,” she said.
Risk for self-harm was more than double in the first 4 weeks after stopping OAT versus stable periods on treatment (aRR, 2.60; 95% CI, 1.83-3.7). Risk for suicide more than quadrupled during this period (aRR, 4.68; 95% CI, 1.63-13.42).
These new results suggest additional interventions may be in order, Dr. Padmanathan noted.
“We already knew that extra care – for example, providing naloxone when coming off OAT – was important to prevent overdoses. But this study suggests providing psychosocial care and other extra care may also be important to prevent suicides,” she said.
There was no statistical evidence of difference between buprenorphine and methadone in terms of self-harm and suicide risks. However, this may be because the sample was not large enough to detect a difference, said Dr. Padmanathan.
Although there are currently no guidelines to indicate an ideal OAT period, previous study results have suggested extending treatment to 2 years may be beneficial, perhaps reducing self-harm and, therefore, suicides, she noted.
“We think most of these adverse outcomes likely occur during short treatment episodes with an unplanned ending. Extending OAT sufficiently to enable a planned ending might help to reduce these risks,” she added.
‘A window of vulnerability’
Authors of an accompanying editorial note the study “adds weight” to the evidence that OAT is a “lifesaving” treatment.
“It’s critical to recognize that transitions in and out of care are vulnerable periods” when it comes to suicide, the coauthor of the editorial, Paul S. Nestadt, MD, department of psychiatry and behavioral sciences, Johns Hopkins University, Baltimore, told this news organization.
Official suicide statistics may not reflect the entire story, as many deaths that occur because of overdose after treatment cessation are not counted as suicides, he said. “It can be difficult for medical examiners to determine if an overdose was intentional or not,” Dr. Nestadt added.
After treatment has been established, physicians “would be wise to delay treatment cessation” until the patient is in a stable condition and can be closely followed by mental health professionals, the editorialists note.
“We must consider the month following OAT cessation to be a window of vulnerability, not just for relapse but also for suicide,” they write.
The finding that patients prescribed OAT have such a high rate of suicide, compared with the general population, is “troubling” and “highlights the importance of interventions which address both opioid use and suicide risk,” they add.
The editorialists point out the median treatment period of 84 days is less than what is generally recommended, raising the question of whether longer treatment might lower suicide risk after treatment discontinuation.
They also emphasized the need for further study to test potential suicide prevention interventions in the period after treatment cessation.
Dr. Nestadt added the new findings are “quite generalizable outside of the U.K.” and referred to similar studies carried out in Australia and elsewhere.
The study was funded by the Medical Research Council. Dr. Padmanathan was a coapplicant on an a grant awarded to University of Bristol by Bristol and Weston Hospital Charity focusing on suicide prevention for patients presenting to the emergency department with self-harm and harmful substance use. Dr. Nestadt has reported no relevant financial relationships.

FROM THE LANCET PSYCHIATRY
Cessation of opioid agonist therapy (OAT) significantly increases the risk of self-harm and death by suicide in the first month after stopping the treatment in new findings that highlight the need for “advanced safety planning” during this critical time.
Investigators found that 4 weeks after stopping OAT, the risk of death by suicide was almost five times higher and the risk of hospital admission for self-harm was almost three times higher during this period, compared with the 4 weeks after initiation of OAT to treatment end.
These results highlight the importance of a “transition” period when stopping OAT and highlight the need for better supports for patients coming off this treatment, study investigator Prianka Padmanathan, MD, PhD candidate, Population Health Sciences, University of Bristol (England), told this news organization.
She noted the study supports previous findings that OAT “has an important role” in suicide prevention.
“Suicide and self-harm risk is greatly increased during treatment cessation, and advanced safety planning and additional psychosocial support during this time may be required,” Dr. Padmanathan said.
The findings were published online Dec. 15 in The Lancet Psychiatry.
Suicide, self-harm risk
Previous research shows an increased risk for overdose deaths and death in general during the first few weeks of starting and stopping treatment for opioid dependence.
“We wanted to see if the risk of dying by suicide was also elevated during these times,” said Dr. Padmanathan. As suicides are relatively rare, the researchers also looked at self-harm, “which is an important risk factor for suicide.”
, particularly buprenorphine or methadone.
“We tried to exclude people prescribed these drugs for pain and focused specifically on their prescription for opioid dependence,” Dr. Padmanathan said.
They estimated rates and adjusted risk ratios of hospital admissions for nonfatal self-harm and completed suicide during treatment initiation, maintenance, and cessation.
The study included 8,070 patients (69.3% men; mean baseline age, 33.3 years) who received OAT at least once from January 1998 through November 2018. The median treatment time was 84 days. Most of the participants lived in the most deprived neighborhoods and were White.
There were 807 hospital admissions for self-harm (1.99 per 100 person-years) and 46 suicides (0.11 per 100 person-years).
The investigators examined age, sex, socioeconomic status, number of previous OAT treatment episodes, previous self-harm, previous mental illness, and major chronic illness scores as potential confounders.
Need for psychosocial care
Results showed the risk for self-harm was significantly increased while off OAT (aRR, 1.5; 95% confidence interval, 1.21-1.88).
The overall age- and sex-standardized mortality ratio for suicide was 7.5 times higher (95% CI, 5.5-10) in the study cohort, compared with the general population in England between 1998 and 2017.
There was insufficient evidence to show the risk for suicide was higher off, versus on, treatment, but this may be because suicides are relatively rare, Dr. Padmanathan noted.
“The sample may have been too small to enable a difference to be detected. In contrast, self-harm is more common, so there was power to detect a difference there,” she said.

Short-acting opioids needed for withdrawal in U.S. hospitals, say experts
The commentary by Robert A. Kleinman, MD, with the Centre for Addiction and Mental Health, and department of psychiatry, University of Toronto, and Sarah E. Wakeman, MD, with the division of general internal medicine at Massachusetts General Hospital, and Harvard Medical School, Boston, was published in Annals of Internal Medicine.
Currently, short-acting opioids are not recommended in the United States for opioid withdrawal symptoms (OWS) management in the hospital, the authors wrote. Instead, withdrawal symptoms are typically treated, followed by methadone or buprenorphine or nonopioid medications, but many patients don’t get enough relief. Undertreated withdrawal can result in patients leaving the hospital against medical advice, which is linked with higher risk of death.
Addiction specialist Elisabeth Poorman, MD, of the University of Illinois Chicago, said in an interview that she agrees it’s time to start shifting the thinking on using short-acting opioids for OWS in hospitals. Use varies greatly by hospital and by clinician, she said.
“It’s time to let evidence guide us and to be flexible,” Dr. Poorman said.
The commentary authors noted that with methadone, patients must wait several hours for maximal symptom reduction, and the full benefits of methadone treatment are not realized until days after initiation.
Rapid initiation of methadone may be feasible in hospitals and has been proposed as an option, but further study is necessary before widespread use, the authors wrote.
Short-acting opioids may address limitations of other opioids
Lofexidine, an alpha-2-adrenergic agonist, is the only drug approved by the Food and Drug Administration specifically for OWS.
“However,” the authors said, “more than half of patients with OWS treated with lofexidine in phase 3 efficacy trials dropped out by day five. Clonidine, another alpha-2-agonist used off label to treat OWS, has similar effects to those of lofexidine. “
Therefore, short-acting opioids may complement methadone and buprenorphine in treating OWS in the hospital by addressing their limitations, the authors wrote.
Dr. Kleinman and Dr. Wakeman also say short-acting opioids may help with starting buprenorphine for patients exposed to fentanyl, because short-acting opioids can relieve withdrawal symptoms while fentanyl is metabolized and excreted.
Supplementation with short-acting opioids within the hospital can relieve withdrawal symptoms and help keep patients comfortable while methadone is titrated to more effective doses for long-term treatment, they wrote.
With short-acting opioids, patients may become more engaged in their care with, for example, a tamper-proof, patient-controlled analgesia pump, which would allow them to have more autonomy in administration of opioids to relieve pain and withdrawal symptoms, the authors wrote.
Dr. Kleinman and Dr. Wakeman noted that many patients who inject drugs already consume short-acting illicit drugs in the hospital, typically in washrooms and smoking areas, so supervised use of short-acting opioids helps eliminate the risk for unwitnessed overdoses.
Barriers to short-acting opioid use
Despite use of short-acting opioids internationally, barriers in the United States include limited prospective, randomized, controlled research on their benefits. There is limited institutional support for such approaches, and concerns and stigma around providing opioids to patients with OUD.
“[M]any institutions have insufficient numbers of providers who are both confident and competent with standard buprenorphine and methadone initiation approaches, a prerequisite before adopting more complex regimens,” the authors wrote.
Short-acting, full-agonist opioids, as a complement to methadone or buprenorphine, is already recommended for inpatients with OUD who are experiencing acute pain.
But the authors argue it should be an option when pain is not present, but methadone or buprenorphine have not provided enough OWS relief.
When short-acting opioids are helpful, according to outside expert
Dr. Poorman agrees and says she has found short-acting opioids simple to use in the hospital and very helpful in two situations.
One is when patients are very clear that they don’t want any medication for opioid use disorder, but they do want to be treated for their acute medical issue.
“I thought that was a fantastic tool to have to demonstrate we’re listening to them and weren’t trying to impose something on them and left the door open to come back when they did want treatment, which many of them did,” Dr. Poorman said.
The second situation is when the patient is uncertain about options but very afraid of precipitated withdrawal from buprenorphine.
She said she then found it easy to switch from those medications to buprenorphine and methadone.
Dr. Poorman described a situation she encountered previously where the patient was injecting heroin several times a day for 30-40 years. He was very clear he wasn’t going to stop injecting heroin, but he needed medical attention. He was willing to get medical attention, but he told his doctor he didn’t want to be uncomfortable while in the hospital.
It was very hard for his doctor to accept relieving his symptoms of withdrawal as part of her job, because she felt as though she was condoning his drug use, Dr. Poorman explained.
But Dr. Poorman said it’s not realistic to think that someone who clearly does not want to stop using is going to stop using because a doctor made that person go through painful withdrawal “that they’ve structured their whole life around avoiding.”
Take-home message
“We need to understand that addiction is very complex. A lot of times people come to us distressed, and it’s a great time to engage them in care but engaging them in care doesn’t mean imposing discomfort or pain on them,” Dr. Poorman noted. Instead, it means “listening to them, helping them be comfortable in a really stressful situation and then letting them know we are always there for them wherever they are on their disease process or recovery journey so that they can come back to us.”
Dr. Wakeman previously served on clinical advisory board for Celero Systems and receives textbook royalties from Springer and author payment from UpToDate. Dr. Kleinman and Dr. Poorman declared no relevant financial relationships.

FROM ANNALS OF INTERNAL MEDICINE
U.S. overdose deaths hit an all-time high
a 28.5% increase from the previous year.
Deaths in some states rose even more precipitously. Vermont saw an almost 70% increase, and drug overdose deaths in West Virginia increased by 62%. Many states, including Alabama, California, Kansas, Kentucky, Louisiana, Tennessee, and Washington, had a 45%-50% rise in overdose deaths.
The data released by the CDC was provisional, as there is generally a lag between a reported overdose and confirmation of the death to the National Vital Statistics System. The agency uses statistical models that render the counts almost 100% accurate, the CDC says.
The vast majority (73,757) of overdose deaths involved opioids – with most of those (62,338) involving synthetic opioids such as fentanyl. Federal officials said that one American died every 5 minutes from an overdose, or 265 a day.
“We have to acknowledge what this is – it is a crisis,” Department of Health & Human Services Secretary Xavier Becerra told reporters on a call.
“As much as the numbers speak so vividly, they don’t tell the whole story. We see it in the faces of grieving families and all those overworked caregivers. You hear it every time you get that panicked 911 phone call, you read it in obituaries of sons and daughters who left us way too soon,” Mr. Becerra said.
Rahul Gupta, MD, director of the White House Office of National Drug Control Policy, said that “this is unacceptable, and it requires an unprecedented response.”
Dr. Gupta, who noted that he has a waiver to treat substance use disorder patients with buprenorphine, said he’s seen “first-hand the heartbreak of the overdose epidemic,” adding that, with 23 years in practice, “I’ve learned that an overdose is a cry for help and for far too many people that cry goes unanswered.”
Both Mr. Becerra and Dr. Gupta called on Congress to pass President Joe Biden’s fiscal 2022 budget request, noting that it calls for $41 billion – a $669 million increase from fiscal year 2021 – to go to agencies working on drug interdiction and substance use prevention, treatment, and recovery support.
Dr. Gupta also announced that the administration was releasing a model law that could be used by state legislatures to help standardize policies on making the overdose antidote naloxone more accessible. Currently, such policies are a patchwork across the nation.
In addition, the federal government is newly supporting harm reduction, Mr. Becerra said. This means federal money can be used by clinics and outreach programs to buy fentanyl test strips, which they can then distribute to drug users.
“It’s important for Americans to have the ability to make sure that they can test for fentanyl in the substance,” Dr. Gupta said.
Fake pills, fentanyl a huge issue
Federal officials said that both fentanyl and methamphetamine are contributing to rising numbers of fatalities.
“Drug cartels in Mexico are mass-producing fentanyl and methamphetamine largely sourced from chemicals in China and they are distributing these substances throughout the United States,” Anne Milgram, administrator of the Drug Enforcement Administration, said on the call.
Ms. Milgram said the agency had seized 12,000 pounds of fentanyl in 2021, enough to provide every American with a lethal dose. Fentanyl is also mixed in with cocaine, heroin, methamphetamine, and marijuana – often in counterfeit pills, Ms. Milgram said.
The DEA and other law enforcement agencies have seized more than 14 million such pills in 2021. “These types of pills are easily accessible today on social media and e-commerce platforms, Ms. Milgram said.
“Drug dealers are now in our homes,” she said. “Wherever there is a smart phone or a computer, a dealer is one click away,” Ms. Milgram said.
National Institute on Drug Abuse Director Nora D. Volkow, MD, said that dealers will continue to push both fentanyl and methamphetamine because they are among the most addictive substances. They also are more profitable because they don’t require cultivation and harvesting, she said on the call.
Dr. Volkow also noted that naloxone is not as effective in reversing fentanyl overdoses because fentanyl is more potent than heroin and other opioids, and “it gets into the brain extremely rapidly.”
Ongoing research is aimed at developing a faster delivery mechanism and a longer-lasting formulation to counter overdoses, Dr. Volkow said.

Deaths in some states rose even more precipitously. Vermont saw an almost 70% increase, and drug overdose deaths in West Virginia increased by 62%. Many states, including Alabama, California, Kansas, Kentucky, Louisiana, Tennessee, and Washington, had a 45%-50% rise in overdose deaths.

Warn patients about illicit drugs doctored with fentanyl
Fentanyl is now threatening overdoses in patients exposed to essentially any of the full array of recreational drugs – not just opioids – that are being sold illicitly, according to an overview of the problem presented at the virtual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
“Fentanyl can now be found in cocaine and methamphetamine. At this point, there is really no way to predict what is in a [street] drug,” Edwin A. Salsitz, MD, said at the meeting, sponsored by Medscape Live. He is associate clinical professor of medicine who works in the division of chemical dependency at Mount Sinai Beth Israel Medical Center in New York.
As proof of the frequency with which fentanyl is now being used as an additive, most patients with a drug use disorder, regardless of their drug of choice, are testing positive for fentanyl at Dr. Salsitz’s center. Many of those with positive fentanyl tests are unaware that their drugs had been doctored with this agent.
Relative to drugs sold as an opioid, such as heroin or oxycodone, the fentanyl dose in nonopioid drugs is typically more modest, but Dr. Salsitz pointed out that those expecting cocaine or methamphetamine often “have no heroin tolerance, so they are more vulnerable” to the adverse effects of fentanyl, including an overdose.
Although opioid tolerance might improve the chances for surviving a fentanyl overdose, the toxicology of fentanyl is not the same as other opioids. Death from heroin is typically a result of respiratory depression, but the onset is relatively slow, providing a greater opportunity to administer a reversal agent, such as naloxone.
Fentanyl not only produces respiratory depression but skeletal muscle rigidity. The rapid onset of “wooden chest syndrome” can occur within minutes, making the opportunity for intervention much smaller, Dr. Salsitz said.
To illustrate the phenomenon, Dr. Salsitz recounted a case.
After an argument with his mother, a 26-year-old male with a long history of intravenous drug use went to his bedroom. His mother, responding to the sound of a loud thud, rushed to the bedroom to find her son on the floor with a needle still in his arm. Resuscitation efforts by the mother and by the emergency responders, who arrived quickly, failed.
“The speed of his death made it clear that it was fentanyl related, and the postmortem toxicology confirmed that the exposure involved both heroin and fentanyl,” Dr. Salsitz said.
After the first wave of deaths in the opioid epidemic, which was attributed to inappropriate use of prescription opioids, the second wave was driven by heroin. In that wave, patients who became addicted to prescription opioids but were having more difficulty gaining access to them, turned to far cheaper and readily available street heroin. The third wave, driven by fentanyl, began several years ago when sellers of heroin began adding this synthetic opioid, which is relatively cheap, to intensify the high.
It is not expected to end quickly. The fentanyl added to heroin was never a prescription version. Rather, Dr. Salsitz said, it is synthesized in laboratories in China, Mexico, and the United States. It is relatively easy to produce and compact, which makes it easy to transport.
Exacerbating the risks that fentanyl poses when added to street drugs, even more potent versions, such as carfentanil, are also being added to cocaine, methamphetamines, and other nonopioid illicit drugs. When compared on a per-milligram basis, fentanyl is about 100 times more potent than heroin, but carfentanil is about 100 times more potent than fentanyl, according to Dr. Salsitz.
When the third wave of deaths in the opioid epidemic began around 2013, prescriptions of fentanyl, like many other opioid-type therapies were declining. The “perfect storm” that initiated the opioid epidemic was a product of intense focus on pain control and a misperception that prescription opioids posed a low risk of abuse potential, Dr. Salsitz said. By the time fentanyl was driving opioid deaths, the risks of opioids were widely appreciated and their use for prescription analgesia was declining.
Citing several cases, Dr. Salsitz noted that only 20 years after clinicians were being successfully sued for not offering enough analgesia, they were now going to jail for prescribing these drugs too liberally.
According to Dr. Salsitz, While psychiatrists might not have a role in this issue, Dr. Salsitz did see a role for these specialists in protecting patients from the adverse consequences of using illicit drugs doctored with fentanyl.
Noting that individuals with psychiatric disorders are more likely than the general population to self-medicate with drugs purchased illegally, Dr. Salsitz encouraged psychiatrists “to get involved” in asking about drug use and counseling patients on the risks of fentanyl substitution or additives.
“The message is that no one knows what are in these drugs, anymore,” he said.
In addition to making patients aware that many street drugs are now contaminated with fentanyl, Dr. Salsitz provided some safety tips. He suggested instructing patients to take a low dose of any newly acquired drug to gauge its effect, to avoid taking drugs alone, and to avoid mixing drugs. He also recommended using rapid fentanyl test strips in order to detect fentanyl contamination.
Even for the many psychiatrists who do not feel comfortable managing addiction, Dr. Salsitz recommended a proactive approach to address the current threat.
Test strips as an intervention
The seriousness of fentanyl contamination of illicit drugs, including cocaine and methamphetamine, was corroborated by two investigators at the School of Public Health and the Albert Einstein Medical School of Brown University, Providence, R.I. Brandon D.L. Marshall, PhD, associate professor of epidemiology in the School of Public Health, called fentanyl-contaminated cannabis “extremely rare,” but he said that it is being found in counterfeit prescription pills as well as in crystal methamphetamine and in both crack and powder cocaine.
He also advocated the use of fentanyl test strips.
“Test strips are an efficient, inexpensive, and effective way to determine whether fentanyl or related analogs are present in illicit drugs,” he said, noting that he is involved in a trial designed to determine whether fentanyl test strips can reduce the risk of fatal and nonfatal overdoses.
In a pilot study conducted in Baltimore, 69% of the 103 participants engaged in harm reduction behavior after using a fentanyl test strip and receiving a positive result (Addict Behav. 2020;110:106529). It is notable that 86% of the participants had a least one positive result when using the strips. More than half were surprised by the result.
One of the findings from this study was “that the lasting benefit of fentanyl test strip distribution is the opportunity to engage in discussions around safety and relationship building with historically underserved communities,” said the lead author, Ju Nyeong Park, PhD, assistant professor of medicine and epidemiology at Brown University. She moved to Brown after performing this work at Johns Hopkins University, Baltimore.
Dr. Park noted that “many patients in the community already know that they are using drugs containing fentanyl,” but for those who are concerned and wish to avoid contaminated drugs, fentanyl test strips “are a quick screening tool.” However, while the strips are helpful, she cautioned that they cannot be considered a definitive tool for detecting harm in illicit drugs.
“There may also be other chemicals present in tested drugs that confer risk,” she said.
