Abstract

This study evaluated the effects of acute doses of zopiclone (7.5 mg), triazolam (0.25 mg) and placebo on memory and psychomotor performance of 12 normal volunteers. The subjects received both drugs in a repeated measure, double-blind Latin square design. The tests (CFF, CRT, DSST, memory assessments) were performed before and 2 and 6 hr after treatment. Zopiclone and triazolam induced an anterograde amnesia affecting short-term and long-term memory which lasted less than 6 hr. No retrograde amnesia was observed. Two hr after drug intake of both hypnotics psychomotor performances were significantly altered compared with placebo. The subjects also felt more drowsy, dizzy, clumsy and tired, and less alert and energetic 2 hr after zopiclone and triazolam compared to placebo. There was no difference between the effects of the two hypnotics at the doses studied.
