Substance use disorders (SUDs) are a growing problem among older adults. Acamprosate, disulfiram, and naltrexone are United States Food and Drug Administration (referred to as FDA) approved for the treatment of alcohol use disorder, and buprenorphine is approved for the treatment of opiate use disorder among adults. However, the data on the use of these medications for the treatment of SUDs among older adults are unclear from randomized controlled trials (referred to as RCTs). A review of the literature indicates that there are only two RCTs that evaluated the use of pharmacologic agents for SUDs among older adults (≥ 50 years). One trial evaluated the use of naltrexone when compared to placebo for the treatment of alcohol use disorder among individuals, 50-70 years in age. The other trial evaluated the use of naltrexone or placebo as adjuncts with sertraline in the treatment of alcohol use disorder among individuals older than 55 years in age. Both trials indicated that the use of naltrexone reduced the rates of relapse among older adults with alcohol use disorder. However, we did not identify any RCTs that studied the use of buprenorphine, acamprosate, or disulfiram for SUDs among older adults. Based on available evidence, it would be safe to conclude that limited data indicate some efficacy for naltrexone in the treatment of alcohol use disorder among older adults. However, data from controlled trials on the use of other medications that are FDA approved for the treatment of SUDs among younger adults are nonexistent among older adults with SUDs.
Core tip: Substance use disorder is a growing problem among the older adult population. Unfortunately, there is very limited controlled research data on pharmacotherapy to help with this situation. Our review indicates benefits for naltrexone in the treatment of alcohol use disorder, but we were not able to find data regarding pharmacotherapy for any other substance use disorder among older adults. This review is our attempt to draw attention towards the topic of substance use disorder treatment among older adults and to encourage further research in this field.
