Some Parkinson's patients will be taking Tasmar (tolcapone)

    Some Parkinson's patients will be taking Tasmar (tolcapone). It's the first drug in a new class...called COMT inhibitors.

    COMT (catechol-O-methyltransferase) is an enzyme that metabolizes levodopa to an INACTIVE metabolite. Blocking this enzyme increases the half-life of levodopa and prolongs its effect.

    Think of Tasmar as a "levodopa booster."
