Gamma-hydroxybutyric acid in the treatment of alcoholism: dosage fractioning utility in non-responder alcoholic patients.
Gamma-hydroxybutyric acid (GHB) has recently been introduced in clinical practice for alcoholism management, due to its utility in inducing abstinence from alcohol. In the present study we investigated the usefulness of greater dosage fractioning of GHB in non-responder alcoholics to the usual three administrations per day. A total of 154 alcoholics were admitted to the study and were treated with GHB (50 mg/Kg orally administered three times per day) for 8 weeks (phase 1); the patients who continued to drink alcohol in phase 1 were administered the same dose of GHB divided into six times per day for another 8 weeks (phase 2). Of the 154 patients, 115 completed phase 1; 78 (67.8%) of these began and maintained abstinence (group A) while 37 subjects (32.2%) continued to drink alcohol (group B) showing a craving significantly higher than group A at the end of phase 1 (P < 0.001); in these patients the major fractioning of the drug in phase 2 caused a significant reduction in craving (P < 0.005) and 26 (70.2%) began and maintained abstinence. Moreover no significant differences in final craving score between group A and B was observed. Within the limits of an open study, our data show that non-responder subjects to the conventional fractioning of GHB seem to benefit from the greater fractioning of the drug and seem to indicate the need for a slow-release form of GHB with a prolonged action.
