Profenamine (INN; also known as ethopropazine (BAN); trade names Parsidol, Parsidan, Parkin) is a phenothiazine derivative used as an antiparkinsonian agent that has anticholinergic, antihistamine, and antiadrenergic actions. It is also used in the alleviation of the extrapyramidal syndrome induced by drugs such as other phenothiazine compounds, but, like other compounds with antimuscarinic properties, is of no value against tardive dyskinesia.
