Revospirone
Revospirone is an azapirone drug which was patented as a veterinary tranquilizer but was never marketed. It acts as a selective 5-HT1A receptor partial agonist. Similarly to other azapirones such as buspirone, revospirone produces 1-piperazine as an active metabolite. As a result, it also acts as an α2-adrenergic receptor antagonist to an extent.
