title: Tolcapone: a review of its use in the management of Parkinson's disease.
abstract: 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. Tolcapone significantly improves levodopa-induced motor fluctuations and significantly reduces levodopa requirements. The drug is generally well tolerated, with the most commonly occurring adverse events being dopaminergic related. Thus, tolcapone is a useful option in patients with fluctuating Parkinson's disease who are receiving levodopa/DDCI and are not responding to, or are not candidates for, other adjunctive treatments.
