Adverse drug event profile of pharmacotherapies for alcohol use disorder: a retrospective pharmacovigilance disproportionality analysis study.

Background: Alcohol Use Disorder (AUD) significantly affects global health, leading to physical deterioration and impacting personal and social relationships. This study aims to evaluate the adverse event profiles (AEP) of three USFDA-approved medications for AUD, acamprosate, disulfiram, and naltrexone, using data from the USFDA Adverse Event Reporting System (AERS).

Research designs and methods: Reports related to acamprosate, disulfiram, and naltrexone from March 2004 to March 2024 were extracted from the USFDA AERS database. Data were verified, and disproportionality analysis was conducted using frequentist and Bayesian methods. Adverse events were assessed based on reporting odds ratio, proportional reporting ratio, and Bayesian measures. Outcomes such as death, life-threatening events, and hospitalization were also analyzed.

Results: A total of 19,177 unique reports were analyzed (naltrexone: n = 18,544; acamprosate: n = 249; disulfiram: n = 384). Common adverse events included hepatobiliary, nervous system, and psychiatric disorders. Disulfiram was associated with coagulopathy and drug interactions, while naltrexone was linked to injection site reactions and hypersensitivity. Naltrexone had higher mortality reports, and disulfiram had more hospitalizations.

Conclusion: The study underscores the diverse AEPs of these medications, highlighting the need for careful monitoring and individualized treatment to ensure safety and efficacy in managing AUD.
