Pirenperone (INN, USAN, BAN; developmental code names R-47456, R-50656) is a serotonin receptor antagonist described as an antipsychotic and tranquilizer which was never marketed.[1][2] It is a relatively selective antagonist of the serotonin 5-HT₂ receptors and has been used in scientific research to study the serotonin system.[2][3] In the 1980s, the drug was found to block the effects of the lysergic acid diethylamide (LSD) in animals, and along with ketanserin, led to the elucidation of the 5-HT_2A receptor as the biological mediator of the effects of serotonergic psychedelics.[4]
