Patent number: RE34579Abstract: The monamine oxidase inhibitor drug L-deprenyl (phenylisopropyl methyl propynyl amine) is safely and conveniently used for the treatment of mental depression in a formulation applied to the skin of the patient. In this way the danger of side reaction due to the consumption of foods containing tyramine (the cheese effect) is minimized. Unlike other monamine oxidase drugs, such as Parnate, L-deprenyl does not cause skin irritation when used in this way.Type: GrantFiled: August 27, 1991Date of Patent: April 5, 1994Assignee: Somerset Pharmaceuticals, Inc.Inventors: Donald A.
