Final answer:
Haloperidol has anticholinergic properties that can cause extrapyramidal symptoms (EPS).
Step-by-step explanation:
Haloperidol, an antipsychotic medication, has anticholinergic properties. Anticholinergic medications block the action of acetylcholine, a neurotransmitter. This can cause several side effects, including extrapyramidal symptoms (EPS). Extrapyramidal symptoms are movement disorders that can include muscle stiffness, tremors, and involuntary muscle movements.
