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.

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
