How does it work?

Benztropine mesylate belongs to a group of medicines called the anti-cholinergics. These medicines block cholinergic receptors in many parts of the body including the brain. It is used in the treatment of Parkinson's disease and to reduce the side effects of certain anti-psychotic medicines. Dopamine is a chemical substance found in the brain, which is known to be deficient in people with Parkinson's disease. Normally, there is a balance between the level of dopamine and another chemical called acetylcholine. A fall in the level of dopamine results in too high levels of acetylcholine. Therefore by blocking acetylcholine receptors with benztropine, this balance can be restored. In this way some of the symptoms of Parkinson's disease may be controlled. Benztropine is most effective at reducing the tremor and rigidity associated with Parkinson's disease, however it has little effect on the slow movements (bradykinesia). It is also useful in relieving symptoms such as drooling, pain and sleep disturbances due to muscle spasm or cramps, mask-like faces, speech and writing difficulties and gait disturbances. Anti-psychotic medicines are used to treat conditions such as schizophrenia by decreasing the amount of dopamine in the brain. If these dopamine levels drop too low, they produce side effects which resemble the symptoms of Parkinson's disease. These side effects are known as extrapyramidal side effects and include abnormal face and body movements, restlessness and tremor. Benztropine is used to reduce these side effects in susceptible individuals.
