Efficacy and tolerance of zopiclone in insomniac geriatric patients.


Zopiclone is a cyclopyrrolone derivative which exerts, in animal and man, an hypnotic activity comparable to that of flurazepam. In healthy adult insomniacs it was well tolerated upon repeated administration for 28 days. In a double-blind, placebo-controlled, crossover study, three dose levels of zopiclone (5, 7.5, and 10 mg) were compared to 15 mg of flurazepam in 30 geriatric insomniacs. The 7.5- and 10-mg doses demonstrated hypnotic potency comparable to that of flurazepam, and the active treatments were superior to placebo. For most sleep indices, 7.5 mg was the optimal therapeutic dose. Few side effects were reported. These were not clinically significant. Zopiclone is efficacious and well tolerated in the treatment of geriatric patients suffering from insomnia. A dosage range of 7.5-10 mg is recommended.
