Ethybenzatropine (Ponalid) is an anticholinergic and antihistaminergic drug. It was used as an antiparkinsonian agent. A significant increase in the duration of action of levodopa-induced improvement in parkinsonian symptoms was observed following the administration of ethybenzatropine. Ethybenzatropine also improved, or tended to improve the duration and seventy of onset and end-of-dose levodopa-induced dyskinesias. Thus when levodopa is administered together with etybenzatropine, its length of action on parkinsonian symptoms is prolonged.

Sample Use Guides

In Vivo Use Guide

Nine patients with Parkinson’s disease: Levodopa was given orally together with a peripheral DOPA-decarboxylase inhibitor at the usual effective morning dosage for each patient. The same dose of levodopa was administered the next day in addition to ethybenzatropine, 5 mg given i.v. Ethybenzatropine was administered between 0 and 15 min after the first dose of levodopa

Route of Administration: Intravenous
