BenzatropineThe Generic name of this drug
Treatment SummaryBenztropine is a medication used to treat the symptoms of Parkinson's disease. It is made up of a combination of a tropane ring, similar to cocaine, and a diphenyl ether, which is known to inhibit dopamine uptake. Studies have shown that adding a chlorine substituent to one of the phenyl rings increases the potency of the drug while also decreasing its inhibition of serotonin and norepinephrine. Benztropine was developed by USL Pharma and approved by the FDA in 1996.

How Benztropine Mesylate Affects PatientsBenztropine increases the amount of dopamine in the brain, resulting in a sedative effect that can last up to 24 hours. It also has antihistamine and anticholinergic properties, which are similar to the effects of pyrilamine and atropine. The effects usually start within an hour or two after taking the drug.
How Benztropine Mesylate works in the bodyBenztropine is a drug with anti-muscarinic and antihistaminic effects. It works by blocking the activity of dopamine transporters, as well as histamine and muscarine receptors in the brain. By blocking these receptors, it helps to restore the balance between dopamine and acetylcholine which is often disrupted in Parkinson's patients.
