Abstract

Medication-assisted behavior treatment for alcohol use disorder (AUD) holds promise to enhance the efficacy of medication and of behavior therapy when administered individually. The present study examines the treatment benefit of combined outpatient naltrexone (NTX) treatment with Alcoholics Anonymous Facilitation (AAF) behavior therapy, in the context of OPRM1 genotype. The minor OPRM1 Asp40 G-allele has been associated with greater positive reinforcing effects of alcohol consumption and greater alcohol craving, suggesting that individuals carrying the OPRM1 G allele may have an improved naltrexone response. Twenty patients, including 7 G-allele carriers, received 90 days of naltrexone with medication support and dispensing sessions, and ten AAF behavior therapy sessions. During treatment and the eight-week posttreatment follow-up, an overall increase in percent days abstinent was observed for the sample as a whole, but G-allele carriers reported relatively heavier drinking relative to other subjects. These findings suggest that this enhanced medication-assisted behavior treatment is a promising therapeutic combination, and mirror other recent findings that G-allele carriers may require more intensive treatment.
