Hexinor 5 mg Tablet is an anticholinergic medication used to manage symptoms of Parkinson's disease and drug-induced extrapyramidal disorders. It contains Trihexyphenidyl Hydrochloride, which works by inhibiting the action of acetylcholine, a neurotransmitter involved in muscle movement regulation. This helps alleviate symptoms such as muscle stiffness, tremors, and involuntary movements associated with Parkinsonism and certain medication-induced movement disorders.
