The side effect of hypotension might be caused by which psychotropic medication?

The side effect of hypotension is commonly associated with Thorazine (chlorpromazine). This medication, which is an antipsychotic, can block alpha-adrenergic receptors, leading to vasodilation and a consequent drop in blood pressure. This side effect is particularly notable in medications that have sedative properties and can also lead to warnings about standing up too quickly due to the risk of orthostatic hypotension.

In contrast, haloperidol, fluoxetine, and paroxetine are less frequently linked with hypotension. Haloperidol is primarily associated with extrapyramidal symptoms and potential tardive dyskinesia, while the selective serotonin reuptake inhibitors like fluoxetine and paroxetine are more often related to side effects such as nausea, insomnia, and sexual dysfunction rather than effects on blood pressure.
