Pheniprazine (INN; also known as amphethydrazine and amphetamine hydrazide; brand names Catron and Cavodil) is an irreversible and nonselective monoamine oxidase inhibitor (MAOI) of the hydrazine chemical class that was used as an antidepressant in the 1960s.[1][2][3] It was also used in the treatment of angina pectoris and schizophrenia.[4][5] Pheniprazine has been largely discontinued due to toxicity concerns such as jaundice, amblyopia, and optic neuritis.[6][7][8]
