Application

Tolcapone may be used in COMT-mediated cell signaling studies.
Tolcapone has been used in methyltransferase assay in human embryonic kidney 293 cells.

Actions biochimiques/physiologiques

Inhibition of catechol-O-methyltransferase by tolcapone increases the half-life and bioavailabilty of levodopa. It therefore is an effective adjunctive therapy in patients with Parkinson′s disease with motor response fluctuations.
Tolcapone is an orally active catechol-O-methyltransferase (COMT) inhibitor. It inhibits both central and peripheral COMT. Tolcapone crosses the blood-brain barrier, and has been used for L-DOPA adjunct therapy in the treatment of Parkinson′s Disease.

Catechol-O-methyltransferase (COMT) inhibitors are drugs commonly used in the management of patients with Parkinson disease complicated by motor fluctuations. Among them, entacapone is the most commonly used. Tolcapone has been reintroduced in patients where entacapone has proved to be ineffective

The relative efficacy has not been adequately established for the two catechol-O-methyltransferase (COMT) inhibitors that are currently available for adjunctive therapy in Parkinson's disease; tolcapone and entacapone. A recent Cochrane meta-analysis of 14 studies in 2566 patients, conducted to assess

Journal of neurology, neurosurgery, and psychiatry, 63(4), 421-428 (1997-10-29)
More than 50% of patients with Parkinson's disease develop motor response fluctuations (the "wearing off" phenomenon) after more than five years of levodopa therapy. Inhibition of catechol-O-methyltransferase by tolcapone has been shown to increase levodopa bioavailability and plasma elimination half

Tolcapone (Tasmar) is a selective, reversible inhibitor of peripheral and central catechol-O-methyltransferase (COMT). Results of well designed studies indicate that oral tolcapone is an effective adjunct to levodopa plus a peripheral dopa-decarboxylase inhibitor (DDCI) in patients with fluctuating Parkinson's disease.
