Trihexyphenidyl (commonly sold as Artane) is an anticholinergic medication used to treat Parkinson's disease and manage severe muscle spasms or extrapyramidal symptoms induced by antipsychotic medications

It improves muscle control, reduces stiffness, and acts as a central nervous system agent.

Treats Parkinson’s Disease: Reduces core symptoms such as tremors (shaking), rigidity (muscle stiffness), and bradykinesia (slowness of movement).

Manages Drug-Induced Movements: Alleviates involuntary muscle spasms (dystonia), restlessness (akathisia), and stiffness caused by certain antipsychotic or anti-nausea medications.

Improves Mobility: Helps restore muscle control and coordination, making it easier to perform daily tasks like walking or standing.
