Influence of combined treatment with naltrexone and memantine on alcohol drinking behaviors: a phase II randomized crossover trial.

ABSTRACT: Glutamate and opioid systems play important roles in alcohol drinking behaviors. We examined if combined treatment with the NMDA antagonist memantine and the opioid antagonist naltrexone, when compared with naltrexone alone, would have a greater influence on alcohol drinking behaviors. Fifty-six, non-treatment-seeking heavy drinkers, with alcohol dependence and a positive family history (FHP) of alcoholism, participated in a randomized, double-blind, crossover trial, including two 6-8 days treatment periods, separated by a 6-day washout, and 3 alcohol drinking paradigm (ADP) sessions. After the first baseline (BAS) ADP1 session, participants were randomized to receive either naltrexone (NTX; 50 mg/day) + placebo memantine, or NTX (50 mg/day) + memantine (MEM; 20 mg/day), during the first t
