Clinical Trials

In a study of 33 patients with insomnia, Dalmane was shown to decrease sleep latency (the time it takes to fall asleep) and increase total sleep time. The mean sleep latency decreased from 30 minutes at baseline to 15 minutes after four weeks of treatment with Dalmane. The mean total sleep time increased from 4.5 hours at baseline to 7.3 hours after four weeks of treatment with Dalmane.
In another study of 100 patients with insomnia, Dalmane was shown to be more effective than placebo in improving sleep. The mean sleep latency decreased from 45 minutes at baseline to 30 minutes after two weeks of treatment with Dalmane. The mean total sleep time increased from 5.1 hours at baseline to 7.3 hours after two weeks of treatment with Dalmane.
Dalmane was well tolerated in both studies. The most common side effects reported were drowsiness and headache.
