Abstract
Background: Once a widely used analgesic in the United States (US), meperidine offered an alternative to other opioids as a pain reliever. However, within the last two decades, meperidine has gone from a drug to be utilized only when patients exhibit atypical reactions to opioids (e.g., morphine and hydromorphone) to being taken off the World Health Organization List of Essential Medications and receiving strong recommendations for the overall avoidance. The aim of this study was to identify changes in meperidine distribution in the US and regional disparities as reported to the Drug Enforcement Administration’s Automation of Reports and Consolidated Orders System (DEA ARCOS) and Medicaid. Methods: Data related to the meperidine distribution was obtained through ARCOS (2001 –2021) and Medicaid public use files (2016 –2021). Heat maps were used to visualize regional disparities in distribution by state. States outside a 95% confidence interval were statistically significant. Results: Meperidine distribution between 2001 and 2021 decreased by 97.4% (R=.-97, P < .0001). There was a 34-fold state-level difference in meperidine distribution between Arkansas (16.8 mg/10 persons) and Connecticut (0.5 mg/ 10 persons) in 2020. Meperidine distribution in 2020 was elevated in Arkansas, Mississippi, and Alabama. In 2021, Meperidine distribution was highest in Arkansas ( 1.67 /10 persons) and lowest in Connecticut (0.08 /10 persons). Total prescriptions of meperidine as reported by Medicaid decreased by 73.8% (R= -0.67, P = 0.045) between 2016 and 2021. Conclusion: We observed a decrease in the overall distribution of meperidine in the past two decades with similar recent declines in prescribing to Medicaid enrollees. The shortage of some parenteral formulations is an important contributor to these declines. This data may reflect plans to phase out the use of this opioid, especially in the many situations where preferred opioids are available.
