Additional recommended knowledge
Benztropine is a centrally acting anticholinergic agent with antihistaminic properties resulting from the combination of the tropine portion of the atropine molecule and the benzohydryl portion of diphenhydramine. Animal studies have indicated that anticholinergic activity of benztropine is approximately one-half that of atropine, while antihistaminic activity approaches that of pyrilamine. Its anticholinergic effects have been established as therapeutically significant in the management of parkinsonism. Benztrop antagonises the effect of acetylcholine, decreasing the imbalance between the neurotransmitters acetylcholine and dopamine, which may improve the symptoms of early Parkinson's disease. 
It is used in patients to reduce the side effects of antipsychotic treatment, such as parkinsonism and akathisia.
Benztropine is also a second-line drug for the treatment of Parkinson's disease. It improves tremor but not rigidity or bradykinesia.
Benztropine is also sometimes used for the treatment of dystonia, a rare disorder that causes abnormal muscle contraction, resulting in twisting postures of limbs, trunk, or face.
These are principally anticholinergic:
Other studies have found no association between anticholinergic exposure and risk of developing tardive dyskinesia.
