What is Trihexyphenidyl Hcl ?

Trihexyphenidyl HCl is an anticholinergic agent used primarily to treat symptoms of Parkinson's disease and extrapyramidal reactions caused by antipsychotic drugs. It works by blocking acetylcholine receptors in the central nervous system, helping to reduce muscle stiffness, sweating, and the production of saliva. The drug is generally administered orally and dosage must be carefully adjusted according to the patient's response and tolerance.
