10 Ways to Stop Stress

GENERIC NAME: buspirone

DISCONTINUED BRAND: Buspar

Buspirone is a medication that is used for the treatment of anxiety. Its mechanism of action is not clearly understood but may involve effects on neurotransmitters, chemicals that nerves use to communicate with one another. Serotonin and dopamine are two of these neurotransmitters. Buspirone may work by stimulating serotonin type 1A receptors on nerves, thereby altering the chemical messages that nerves receive. It also has minor effects on dopamine receptors, but this does not contribute much to its action. Unlike medications for anxiety of the benzodiazepine class, for example, diazepam (Valium), lorazepam (Ativan), alprazolam (Xanax), and clonazepam (Klonopin), buspirone does not cause sedation. The FDA approved buspirone in September 1986.

PRESCRIBED FOR: Buspirone is used for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety. Buspirone is especially effective in persons with generalized anxiety of a limited or moderate degree. It is not very effective in persons with severe anxiety, panic disorders, or obsessive-compulsive disorders. It also may help improve symptoms of depression in patients with generalized anxiety disorder.

SIDE EFFECTS: The most common side effects associated with buspirone are:
