Opicapone is a selective and reversible catechol-O-methyltransferase (COMT) inhibitor indicated as adjunctive therapy to levodopa/carbidopa in adult patients with Parkinson’s disease with end-of-dose motor fluctuations. It is orally administered and approved in several countries for this purpose.
Pharmacokinetics
Healthy adult volunteers, following single oral administration of opicapone 50 mg.
