Pargyline, sold under the brand name Eutonyl among others, is a monoamine oxidase inhibitor (MAOI) medication which has been used to treat hypertension (high blood pressure) but is no longer marketed.[4][5][6] It has also been studied as an antidepressant, but was never licensed for use in the treatment of depression.[7][8] The drug is taken by mouth.[1][2]

Side effects of pargyline include orthostatic hypotension among others.[1] It has the potential for serious food and drug interactions with sympathomimetic agents like tyramine that can result in hypertensive crisis.[1] Pargyline acts as a non-selective and irreversible inhibitor of the monoamine oxidases MAO-A and MAO-B.[6] The exact mechanism of the hypotensive effects of pargyline and other MAOIs is unclear.[9][10][11][12] Structurally, pargyline is a benzylamine derivative and is related to selegiline and clorgyline.[13][14][15]

Pargyline was first described in 1960[9][16][17] and was introduced for medical use in 1963.[18] It was available in the United States and the United Kingdom.[18][2][5] The clinical use of pargyline was limited due to its side effects and interactions.[1] The drug remained available in the United States as late as 2000.[5] However, it was fully discontinued worldwide by 2007.[19]
