Buspirone does not produce a 5-HT1A-mediated decrease in temperature in man

Abstract

Buspirone, a putative serotonin (5-HT)_1A partial agonist, did not produce hypothermia in 17 normal volunteers in a placebo controlled, single blind study. Thus, buspirone may be a weaker agonist at those 5-HT_1A receptors which mediate hypothermia compared to ipsapirone or gepirone, two other 5-HT_1A partial agonists which have been reported to produce hypothermia by a 5-HT_1A-mediated mechanism.
