Selegiline, also known as L-deprenyl is a substituted phenethylamine that at normal clinical doses it is a selective irreversible MAO-B inhibitor. In larger doses it loses its specificity and also inhibits MAO-A. It is available in pill form under many brand names and is used to reduce symptoms in early-stage Parkinson's disease. A transdermal patch (brand name, Emsam) is used to treat depression.
