How does Trihexyphenidyl work in the body?
Trihexyphenidyl works by blocking the action of acetylcholine, a neurotransmitter in the brain that is involved in the regulation of movement. By inhibiting acetylcholine, Trihexyphenidyl helps to restore the balance between acetylcholine and dopamine, another neurotransmitter, thereby reducing the symptoms of Parkinson's disease and other movement disorders. This mechanism of action helps improve muscle control and reduce stiffness and tremors.
