DescriptionOpicapone is a potent, reversible, and peripherally-acting third-generation inhibitor of catechol-o-methyltransferase (COMT), an enzyme involved in the breakdown of various catecholamines including dopamine.[A36938, A203048] Many patients with Parkinson’s disease treated with levodopa plus a dopa decarboxylase (DDC) inhibitor (eg carbidopa) experience motor complications over time, which calls for the management of these symptoms through the use of a dopamine agonist, a monoamine oxidase B inhibitor (selegiline, rasagiline), a _catechol-O-methyl transferase (COMT)_ inhibitor, or amantadine, or using a modified-release formulation of levodopa.[L2336] Opicapone is used for adjunct therapy to levodopa and carbidopa in adult patients with Parkinson's disease and end-of-dose motor fluctuations. Opicapone was approved for use by the European Commission in June 2016 [L2339] and the FDA in April 2020.[L13772] It is marketed under the brand name Ongentys as once-daily oral capsules. Exhibiting a long duration of action that exceeds 24 hours, opicapone can be administered once-daily [L2336] and demonstrates the lowest risk for cytotoxicity compared to other catechol-O-methyltransferase inhibitors.[A203048]
