Extrapyramidal symptoms (EPS) are a common and often distressing side effect of certain medications, with up to a third of patients on some typical antipsychotics experiencing them. The answer to *why are they called EPS?* is rooted in the neuroanatomy of the brain's motor control systems and the mechanism of these drugs.

Originally developed in the mid-20th century, benzhexol (also known as trihexyphenidyl) has been used in clinical settings for decades to manage various motor dysfunctions. It is primarily recognized as a treatment for the tremors and muscle stiffness associated with Parkinson's disease and certain drug-induced movement disorders.
