Ethopropazine is an anticholinergic drug. Ethopropazine is an inhibitor of butyrylcholinesterase and non-selective muscarinic acetylcholine receptor antagonist. Ethopropazine has been used for the treatment of parkinsonism and drug-induced extrapyramidal reactions. Also It used for the symptomatic treatment of hepatolenticular degeneration and congenital athetosis.

In Vivo Use Guide

ETHOPROPAZINE HYDROCHLORIDE TABLETS USP Usual adult and adolescent dose Parkinsonism and Drug-induced extrapyramidal reactions Oral, 50 mg one or two times a day, the dosage being increased as needed and tolerated. In severe cases, the dose may be increased gradually to a total of 500 to 600 mg a day.

Route of Administration: Oral

In Vitro Use Guide

The racemate and the enantiomers of ethopropazine were tested in vitro for their cellular toxicity using lung fibroblast cells. Each enantiomer was shown to be cytotoxic at concentrations greater than 10 uM.
