Acamprosate and Baclofen were Not Effective in the Treatment of Pathological Gambling: Preliminary Blind Rater Comparison Study

摘要

>Objectives: Pathological gambling (PG) is a highly prevalent and disabling impulse control disorder. A range of psychopharmacological options are available for the treatment of PG, including selective serotonin reuptake inhibitors, opioid receptor antagonists, anti-addiction drugs, and mood stabilizers. In our preliminary study, we examined the efficacy of two anti-addiction drugs, baclofen and acamprosate, in the treatment of PG. >Materials and Methods: Seventeen male gamblers were randomly divided into two groups. Each group received one of the two drugs without being blind to treatment. All patients underwent a comprehensive psychiatric diagnostic evaluation and completed a series of semi-structured interviews. During the 6-months of study, monthly evaluations were carried out to assess improvement and relapses. Relapse was defined as recurrent gambling behavior. >Results: None of the 17 patients reached the 6-months abstinence. One patient receiving baclofen sustained abstinence for 4 months. Fourteen patients succeeded in sustaining abstinence for 1–3 months. Two patients stopped attending monthly evaluations. >Conclusion: Baclofen and acamprosate did not prove efficient in treating pathological gamblers.
