Which medication is most likely to cause symptoms of poor muscle coordination and slow movements?

Haloperidol is an antipsychotic medication that belongs to the class of drugs known as butyrophenones. One of the known side effects of haloperidol is the development of extrapyramidal symptoms (EPS), which can include poor muscle coordination and slowed movements, a condition known as bradykinesia. These symptoms arise due to the drug's antagonistic effects on dopamine receptors in the brain, particularly in areas that are involved in coordinating movement.

Patients receiving haloperidol may experience additional motor side effects, such as tremors, rigidity, and abnormal postures, collectively attributable to the disruption of the dopamine pathways that regulate motor control. This can lead to noticeable changes in coordination and movement speed. Understanding the side effects associated with antipsychotic medications is essential, particularly in monitoring and managing a patient's overall well-being.
