Anxiolytic

An anxiolytic is any drug used in the treatment of anxiety. Azapirones[?], benzodiazepines, tranquillizers and even barbiturates, non-cardioselective Beta blockers[?], antihistamines[?] or meprobamate[?] can be prescribed. For somatic symptoms propranlol and oxprenolol can be used.

Azapirones, such as Buspirone, are most commonly prescribed. They chemically quite different from most of the other anxiolytics and the adverse effects of dependence, sedation and psychomotor impairment are noticably less than with benzodiazepines.

Benzodiazepines are prescribed for short-term relief (FDA recommended maximum of 8 months for most benzodiazpeines) of severe and disabling anxiety. Common medications are Valium (diazepam)and Xanax (alprazolam). They are used to treat a wide variety of conditions/symptoms, and usually a first choice any time short term CNS sedation is needed. Longer term uses include severe anxiety and psychosis. The risk of withdrawal symptoms and rebound syndrome is high after only a few weeks. There is an added problem of the accumulation of drug metabolites and adverse effects.

Certain herbs, such as St. John's Wort, may also be used as anxiolytics. St. John's Wort is generally thought to be a mild Selective Serotonin Reuptake Inhibitor[?], or SSRI, like the prescription medications Prozac (fluoxetine) and Paxil (paroxetine).
