Abstract

We describe 2 patients with Parkinson's disease who developed hepatotoxicity associated with the use of entacapone, a novel, mainly peripheral acting inhibitor of catechol-D-methyltransferase. Hepatotoxicity resolved rapidly with discontinuation of the drug. Analysis of causality in a further case initially linked to entacapone exposure was confounded by conflicting serial adverse reaction reports. © 2002 Movement Disorder Society
