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.

Pharmacology
IndicationFor use as an adjunct in the therapy of all forms of parkinsonism and also for use in the control of extrapyramidal disorders due to neuroleptic drugs.
PharmacodynamicsBenztropine is an anticholinergic used in the symptomatic treatment of all etiologic groups of parkinsonism and drug-induced extrapyramidal reactions (except tardive dyskinesia). Benztropine possesses both anticholinergic and antihistaminic effects, although only the former has been established as therapeutically significant in the management of parkinsonism. Benztropine's anticholinergic activity is about equal to that of atropine. Benztropine also inhibits dopamine reuptake via the dopamine transporter at nerve terminals.
Mechanism of actionBenztropine is a selective M1 muscarinic acetylcholine receptor antagonist. It is able to discriminate between the M1 (cortical or neuronal) and the peripheral muscarinic subtypes (cardiac and glandular). Benztropine partially blocks cholinergic activity in the CNS, which is responsible for the symptoms of Parkinson's disease. It is also thought to increase the availability of dopamine, a brain chemical that is critical in the initiation and smooth control of voluntary muscle movement.

antagonist
General Function:
Histamine receptor activity
Specific Function:
In peripheral tissues, the H1 subclass of histamine receptors mediates the contraction of smooth muscles, increase in capillary permeability due to contraction of terminal venules, and catecholamine release from adrenal medulla, as well as mediating neurotransmission in the central nervous system.
