Which type of drug is commonly used to treat hypertension?

ACE inhibitors are a class of medications specifically designed to treat hypertension by blocking the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. By inhibiting this conversion, ACE inhibitors promote vasodilation, thereby lowering blood pressure. They also help reduce the workload on the heart and have protective effects on various organs, particularly the kidneys, making them a preferred choice in managing high blood pressure.

Other classes of medications mentioned, such as antidepressants, antibiotics, and antipyretics, do not have a primary role in treating hypertension. Antidepressants primarily address mood disorders, antibiotics target bacterial infections, and antipyretics are used to reduce fever. Hence, ACE inhibitors are recognized for their specific action in managing hypertension effectively.
