Buspirone

Buspirone is a selective anxiolytic, with minimal CNS depressant effects (it does not affect driving skills) and has no anticonvulsant or muscle relaxant properties. The drug interacts with the 5-HT1A subclass of brain serotonin receptors as a partial agonist, but the precise mechanism of its anxiolytic effect is unknown.it has a slow onset of action (>1 week) and is used in gads, but is less effective in panic disorders. Tolerance development is minimal with chronic use, and there is little rebound anxiety or withdrawal symptoms on discontinuance
