Benztropine is a medication used to treat movement disorders that occur from unknown causes or from the continuous use of antipsychotics.
These movement disorders are known as dystonia and parkinsonism. Benztropine, however, is not beneficial for tardive dyskinesia.
It is taken by mouth or by injection into a vein or muscle.
Benztropine belongs to a class of medications known as anticholinergic drugs.
Anticholinergics work by reducing the amount of the chemical acetylcholine throughout the body.
Acetylcholine is one of the chemicals responsible for muscle contractions, and thus without unnecessary muscle contractions and movements, people with Parkinson’s disease, for example, may be able to walk better.
Benztropine is sometimes referred to by its trade name Cogentin.
