Metrenperone (INNTooltip International Nonproprietary Name, USANTooltip United States Adopted Name, BANTooltip British Approved Name; developmental code name R-50970) is a serotonin 5-HT2 receptor antagonist which was never marketed.[1][2] The drug also shows lower affinity for the α1-adrenergic and histamine H1 receptor and much lower affinity for the dopamine D2 receptor, but no affinity for the serotonin 5-HT1 and muscarinic acetylcholine receptors.[2] It is a weak antagonist of the α1-adrenergic receptor in addition to its potent serotonin 5-HT2A receptor antagonism.[3] Metrenperone has been investigated for use in veterinary medicine to treat acute respiratory distress in cattle and has also been studied for topical treatment of wounds as well as injuries.[1][4][5] It was first described in the scientific literature by 1982.[2]
