| Description | Benzotropine is a centrally-acting, antimuscarinic agent used as an adjunct in the treatment of Parkinson's disease. It may also be used to treat extrapyramidal reactions, such as dystonia and Parkinsonism, caused by antipsychotics (e.g. phenothiazines). Symptoms of Parkinson's disease and extrapyramidal reactions arise from decreases in dopaminergic activity which creates an imbalance between dopaminergic and cholinergic activity. Anticholinergic therapy is thought to aid in restoring this balance leading to relief of symptoms. In addition to its anticholinergic effects, benztropine also inhibits the reuptake of dopamine at nerve terminals via the dopamine transporter. Benzotropine also produces antagonistic effects at the histamine H1 receptor. |
