How Perkinil 5 works

Perkinil 5 is a muscle-relaxing medication. It works by decreasing the activity of excess acetylcholine in the brain. This improves muscle control and reduces stiffness. It helps patients with Parkinson’s disease by improving muscle control and reducing stiffness so that they can move more naturally. It is also used to treat movement disorders (restlessness, involuntary movements, or muscle spasms) which can be caused by certain drugs.
