Metabolite Identification
Common Name5-Hydroxybuspirone
Description5-Hydroxybuspirone belongs to the class of organic compounds known as n-arylpiperazines. These are organic compounds containing a piperazine ring where the nitrogen ring atom carries an aryl group. 5-Hydroxybuspirone is a very strong basic compound (based on its pKa). 5-Hydroxybuspirone is a metabolite of buspirone. Buspirone is an anxiolytic psychoactive drug of the azapirone chemical class, and is primarily used to treat generalized anxiety disorder (GAD) Bristol-Myers Squibb (BMS) gained FDA approval of buspirone in 1986 for treatment of GAD. The patent on Buspar by Bristol-Myers Squibb expired in 2001, and buspirone is available as a generic.
