MAOI
Extracted from the Wikipedia article Monoamine oxidase inhibitor.
MAOI selectivity can vary by dose, route, formulation, and systemic exposure. For example, selegiline is relatively selective for MAO-B at lower doses used in Parkinson's disease, but at higher antidepressant doses also inhibits MAO-A and can function clinically as a non-selective MAOI.
