Which type of medication is commonly used for managing high blood pressure?

ACE inhibitors are commonly used to manage high blood pressure because they work by inhibiting the angiotensin-converting enzyme, which plays a crucial role in the renin-angiotensin-aldosterone system (RAAS). This system regulates blood pressure by controlling the constriction of blood vessels and the retention of sodium and water in the body.

By blocking this enzyme, ACE inhibitors lead to the relaxation of blood vessels, resulting in a decrease in blood pressure. Additionally, they help to reduce the workload on the heart, making them particularly beneficial for individuals with heart conditions that often accompany hypertension.

In contrast, antibiotics are designed to combat bacterial infections, corticosteroids are utilized for inflammatory conditions and immune system disorders, and antihistamines primarily address allergy symptoms. Thus, ACE inhibitors are specifically tailored for the management of hypertension, differentiating their function from those of the other medication types listed.
