Selegiline is a selective, irreversible MAO-B inhibitor at therapeutic doses (5-10 mg/day oral), used for Parkinson's disease and major depressive disorder. At higher doses (>20 mg/day), selectivity is lost and it inhibits both MAO-A and MAO-B, increasing risk of hypertensive crisis with tyramine-rich foods. The transdermal form (Emsam) is used for depression and has less dietary restriction at lower doses due to reduced first-pass metabolism. Metabolizes to L-methamphetamine and L-amphetamine, which may cause mild stimulant effects. Dangerous interactions with serotonergic drugs (SSRIs, SNRIs, TCAs, MDMA, tramadol) and certain opioids (meperidine).
