What is temazepam, and what is it used for?

Temazepam is a drug that is used for treating anxiety. It is in the benzodiazepine class of drugs, the same family that includes diazepam (Valium), alprazolam (Xanax), clonazepam (Klonopin), flurazepam (Dalmane), lorazepam (Ativan), and others.

Temazepam and other benzodiazepines act by enhancing the effects of gamma- aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter (a chemical messenger that nerve cells use to communicate with each other) that inhibits many of the activities of the brain. It is believed that excessive activity in the brain may lead to anxiety or other psychiatric disorders and that temazepam reduces the activity. Temazepam increases total sleep time.

The FDA approved temazepam in February 1981.
