Benzhexol (also known as Trihexyphenidyl) belongs to the antimuscarinic class of drugs.
Explanation:
Benzhexol is an antispasmodic medication primarily used to treat the symptoms of Parkinson's disease, such as stiffness, tremors, spasms, and poor muscle control. Its therapeutic effect stems from its ability to block the action of acetylcholine, a neurotransmitter, at muscarinic receptors. This blockage helps to reduce the excessive cholinergic activity that contributes to the motor symptoms observed in Parkinson's disease. Therefore, it's classified as an antimuscarinic agent.
