Assessing the efficacy of medical treatments for alcohol use disorders

Comparing Treatments of Alcoholism on Craving and Biochemical Measures of Alcohol Consumptions

An open randomized study was conducted to compare different treatments of alcoholism on ethanol intake, craving, and on biochemical measures of alcohol consumptions. Eighty-six alcoholics were abstinent for a mean of two weeks prior to random assignment to g-hydroxybutyrate (GHB, 50 mg/kg of body weight t.i.d), naltrexone (NTX, 50 mg/day) or disulfiram (DSF, 200 mg/ day) treatment for 12 months. All treatments were equally effective in reducing alcohol intake and in maintaining abstinence. In all patients, the treatments were able to reduce both craving and the altered biological markers of alcohol abuse. The maximum effects were observed in GHB-treated patients. The results of the present study suggest that GHB might act both as anticraving and cellular protector agent.

Natural medicines for alcoholism treatment: a review

Alcoholism is a serious problem throughout the world. The development of alcoholism remedies have medical, social and economical significance. In view of the pitfalls of psychological dependence and adverse behavioural effects of synthetic drugs, the development of low toxicity and high efficiency medicines derived from natural products exhibits expansive market prospects. Based on these considerations, we summarize briefly folk application of traditional hangover remedies and clinical application of herbal complex and patent medicines for alcoholism treatment. We have reviewed the effects of natural medicines on intake, absorption and metabolism of alcohol, as well as the protective effects on alcohol-induced acute and chronic tissue injury.

Effect of oral naltrexone on pruritus in cholestatic patients

AIM: To determine the efficacy and potential complications of oral naltrexone used in the treatment of pruritus in cholestatic patients and to compare them with other studies.

METHODS: Thirty-four enrolled cholestatic patients complaining of pruritus were studied. In the initial phase, pruritus scores during day and night were e v a l u a t e d . Subsequently, patients were given a placebo for one week followed by naltrexone for one week. In each therapeutic course (placebo or naltrexone) day and night pruritus scores were distinguished by a visual analogue scale (VAS) system and recorded in patients’ questionnaires.

RESULTS: Both naltrexone and placebo decreased VAS scores significantly. Naltrexone was more effective than placebo in decreasing VAS scores. Both day and night scores of pruritus decreased by half of the value prior to therapy in thirteen patients (38%). Daytime pruritus improved completely in two patients (5.9%), but no improvement in the nighttime values was observed in any patient.

Sixteen patients (47%) suffered from naltrexone complications, eleven (32%) of them were related to its withdrawal. Complications were often mild. In the case of withdrawal, the complication was transient (within the first 24-28 h of therapy) and self-limited. We had to cease the drug in two cases (5.9%) because of severe withdrawal symptoms.

CONCLUSION: Naltrexone can be used in the treatment of pruritus in cholestatic patients and is a safe drug showing few, mild and self-limited complications.
