Opicapone is a novel third generation catechol-O-methyltransferase (COMT) inhibitor, providing potent and sustained COMT inhibition. This action enhances the beneficial effects of levodopa in Parkinson’s disease patients with motor fluctuations. Opicapone is supported by a large and comprehensive clinical development programme. Data from the pivotal studies BIPARK I and II has been presented at various international scientific congresses. The Opicapone EU marketing authorization application has been successfully validated and is now under review by the European Medicines Agency (EMA).

Parkinson's disease is a degenerative disorder of the central nervous system characterized by bradykinesia (slowness of movement), tremor, muscle rigidity and postural instability. The clinical manifestations usually start after the age of 50 years and the incidence increases with age. The prevalence is estimated at 300 per 100,000 inhabitants, increasing to 1/100 over the age of 55–60 years.
