Which of the following medications is commonly prescribed for hypertension?

Amlodipine is commonly prescribed for hypertension because it is a calcium channel blocker. This class of medication works by relaxing the muscles of the blood vessels, thereby allowing them to dilate and reduce blood pressure. It is effective in managing high blood pressure and is often used in combination with other antihypertensive agents to achieve better control of blood pressure levels.

In contrast, the other medications listed serve different purposes: Metformin is primarily used for the management of type 2 diabetes, Fluoxetine and Sertraline are both selective serotonin reuptake inhibitors (SSRIs) indicated for the treatment of depression and anxiety disorders. Their primary action is related to mood regulation rather than blood pressure control, which highlights why Amlodipine is the appropriate choice for treating hypertension.
