 PGD is a prominent and growing social problem. Unfortunately, there is no established drug treatment for this disorder. Preliminary investigations demonstrate that naltrexone in doses up to 250 mgday is well tolerated and safe during an 11-week period and may be a viable treatment option for PGD patients with severe urges. The implications of this study extend from PGD to other impulse control disorders, including compulsive shopping, kleptomania, and possibly alcoholism.
