Zopiclone, a novel cyclopyrrolone compound has recently become available for the treatment of insomnia in Singapore. Pharmacodynamic and pharmacokinetic studies have shown it to be an effective hypnotic with a good safety profile and minimal side-effects. The efficacy of Zopiclone was studied in a group of patients with insomnia (n = 40). The study group comprised patients with and without a psychiatric diagnosis. About two-thirds (65%) of the patients had been on hypnotics previously without relief of the insomnia. There was improvement in the various sleep parameters studied: sleep latency, sleep duration, night awakening, sleep quality, dreams, "day-after" effects. The drug was well-tolerated and only four patients experienced minor side-effects.
