Treatment With Mecamylamine in Smoking and Non-smoking Alcohol Dependent Patients



Trial Phase

Trial Purpose and Description

Trial Purpose

The purpose of the study will be to evaluate the efficacy of mecamylamine in reducing alcohol consumption in smoking and non-smoking alcohol dependent patients.

We hypothesize that mecamylamine will result in a greater reduction of alcohol consumption than placebo. We further hypothesize that mecamylamine will be effective in reducing both alcohol consumption and smoking in a subset of alcoholics who also smoke.
