What is oxazepam-oral, and how does it work (mechanism of action)?

  • Oxazepam (Serax, Zaxopam) is a member of a class of anti-anxiety medications called benzodiazepines. Other members of the benzodiazepine class include alprazolam (Xanax), chlordiazepoxide (Librium), clobazam (Onfi), diazepam (Valium), estazolam (Prosom), flurazepam (Dalmane), midazolam (Versed), lorazepam (Ativan), temazepam (Restoril), and triazolam (Halcion). It helps relieve anxiety by enhancing the activity of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter (a chemical that nerve cells use to communicate with each other) that inhibits activity in the brain. It is thought that excessive activity of nerves in the brain may be the cause of anxiety and other psychological disorders. Benzodiazepines such as oxazepam help to relieve anxiety by increasing the effects of GABA in the brain and spinal cord.
