Hexinor 1 mg Tablet is an anticholinergic medication prescribed for the management of Parkinson's disease and drug-induced extrapyramidal symptoms. The active ingredient, Trihexyphenidyl Hydrochloride, functions by inhibiting the action of acetylcholine, a neurotransmitter responsible for muscle movement regulation. By reducing acetylcholine activity, Hexinor helps alleviate symptoms such as muscle stiffness, tremors, and involuntary movements associated with Parkinsonism and certain medication-induced movement disorders.
