How Hexinor 2 works
Hexinor 2 is an anticholinergic medication. It works by decreasing the activity of a chemical messenger (acetylcholine) in the brain. This improves muscle control and reduces stiffness in Parkinson's disease. It also improves movement disorder (restlessness, involuntary movements or muscle spasm) caused by certain other medicines.
