What is a common side effect of medications ending in "-zine"?

Medications that end in "-zine" typically belong to the class of phenothiazines, which are primarily used as antipsychotics. A well-known group within this class includes drugs such as chlorpromazine and prochlorperazine. One of the common side effects associated with these medications is the development of extrapyramidal symptoms, which can lead to Pseudo-Parkinson's effects.

These effects may include symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability, resembling the characteristics of Parkinson's disease but occurring as a side effect of the medication rather than as a primary neurological disorder. This is attributed to the mechanism of action of these drugs, which can block dopamine receptors in the brain, particularly in pathways that control movement.

In contrast, the other options do not align with the known side effects of medications ending in "-zine". Insomnia and weight loss are not common results of these types of medications; instead, sedation and weight gain are more frequently observed. Increased appetite is not typical for the class either, as many patients may experience a decrease in appetite or weight gain due to the sedation effects of the medications. Thus, understanding the pharmacological effects of
