Opicapone (Ongentys) is a selective and reversible peripheral catechol-O-methyltransferase (COMT) inhibitor. It was first approved in the United States in 2020 and is mainly used as an adjunctive therapy to levodopa/carbidopa to help patients with Parkinson's disease (PD) improve "off" period symptoms. As a strictly controlled prescription drug, its circulation and use are subject to multiple regulatory restrictions.
