Abstract

The safety and efficacy of 10 or 20 mg/day zolpidem, a new hypnotic belonging to the imidazopyridine class, were studied over a 180-day period in 96 patients with sleep disorders. The treatment was continued for a further 180 days by 49 of these patients. Follow-up information from 21 patients who discontinued treatment after 180 days showed no rebound insomnia or withdrawal signs. Efficacy of treatment with respect to reduction of sleep onset latency and number of nocturnal wakenings, and improvement in duration of sleep, quality of sleep and morning wakenings was found in nearly 90% of patients and was maintained in those patients who continued treatment for 360 days. This efficacy was achieved with a stable percentage of patients receiving 10 mg/day and 20 mg/day zolpidem from day 30 to the final visit. Zolpidem, therefore, has been shown to be an effective and safe hypnotic, and to be devoid of rebound and withdrawal effects.
