Mecamylamine for the Treatment of Patients With Depression & Alcohol

Status Completed

Clinical Trial Summary

The objective of this study is to evaluate the efficacy of mecamylamine (MEC, 10 mg/day) versus placebo in reducing depressive and alcohol symptoms in patients with depression and co-morbid alcohol dependence. The researchers hypothesize that MEC will significantly reduce depressive symptoms and decrease alcohol consumption compared to placebo in patients with depression and alcohol dependence who are on a stable dose of a selective serotonin reuptake inhibitor (SSRI).

Clinical Trial Description

Depression with co-morbid alcohol dependence is very prevalent and it is very costly to treat. The co occurrence of the two disorders leads to greater severity and worse long-term outcome, including suicide. Although a number of treatment strategies have been implemented for depressed patients with alcohol dependence the controversy concerning best treatment options for those patients persists.

The clinical relationship between depression and alcohol dependence suggests some common mechanism underlying both disorders. It has been hypothesized that medications that block presynaptic nAChR may be effective in the treatment of alcoholism and depression. Mecamylamine (Inversine ®) is a noncompetitive, high affinity nAChR antagonist with low selectivity for the alpha-7 receptor. Mecamylamine has never been investigated as an effective adjunct treatment for dually diagnosed patients with depression and alcohol dependence. Methods: Thirty participants with a current diagnosis of depression and alcohol dependence will be recruited for this 12-week treatment study. Fifteen participants will be randomized to mecamylamine and fifteen to placebo. Participants will be included in the study if: they meet current DSM-IV criteria for Major Depression and Alcohol Dependence and have been on a stable SSRI dose for 2 weeks. All participants will come weekly to take their medications and complete weekly assessments. Weekly assessments will consist of questioners that will assess depressive symptoms and alcohol consumption over the entire treatment period. Significance: This study is the first to evaluate the efficacy of mecamylamine as an augmenting agent for treatment of depression and alcohol dependence. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
