Dose effects of temazepam tablets on sleep.
The dose effects of temazepam tablets (15 and 30 mg) were studied at two sleep centres in 48 volunteers who had objective polysomnographic evidence of sleep onset insomnia. Volunteers slept in the laboratory, retiring at their usual bedtime after taking placebo or temazepam 30 min earlier, and were monitored for 8 h using standard polysomnographic techniques. Acute (nights 5-7) and short term (nights 11-13) temazepam, both 15 and 30 mg, improved the sleep of these volunteers by reducing sleep latency and increasing sleep time compared to the placebo baseline (nights 2-4). Dose differences were found primarily on the measurement of sleep staging, with 30 mg having a greater or more consistent effect than 15 mg. No residual effects were observed on the basis of questionnaires and objective tests of performance and no consistent evidence of disturbed sleep after discontinuing treatment was seen.
