Hypnotics and hangovers: a pilot study of chlormezanone in general practice

Abstract

Ten patients were included in this pilot study of chlormezanone, assessing its effects on duration and quantity of sleep and daytime performance using a pursuit rotor and a digit symbol test. Comparisons of the sleep assessments favoured chlormezanone, although the differences were not statistically significant. There was no evidence of any reduction in daytime performance after chlormezanone. The comparison of chlormezanone and placebo on the pursuit rotor test and the visual analogue assessment of hangover both slightly favoured the drug, but there were no significant differences. The study has demonstrated that it is feasible to evaluate hypnotic drugs more exactly in general practice.
