Conditions alcohol dependence, bipolar disorder
Treatments acamprosate, placebo
Phase phase 4
Sponsor Medical University of South Carolina
Collaborator Forest Laboratories
Start date April 2007
End date February 2010
Trial size 40 participants
Trial identifier NCT00466661, HR#16928


To conduct a double-blind, randomized, placebo-controlled outpatient clinical trial of acamprosate in individuals with alcohol dependence and bipolar disorder who are also receiving mood stabilizing medication. The study will assess the safety and efficacy of acamprosate in alcohol-dependent bipolar patients as measured by its effects on alcohol use and mood symptoms relative to placebo.

The primary hypothesis to be tested is whether individuals with comorbid bipolar disorder and alcohol dependence who receive acamprosate plus mood stabilizer will have greater improvement in alcohol-related outcomes than those who receive mood stabilizer alone. A secondary hypothesis that will be explored is that alcohol-dependent bipolar individuals treated with acamprosate will have greater mood stability as compared to those treated with mood stabilizers alone.
