Beta-blockers are commonly used to manage hypertension. These medications work by blocking the effects of adrenaline on the beta-adrenergic receptors in the heart, leading to a decrease in heart rate and cardiac output, ultimately reducing blood pressure.

Additionally, ACE inhibitors are also standard treatments for hypertension. They function by inhibiting the enzyme that converts angiotensin I to angiotensin II, a peptide that constricts blood vessels. By reducing the production of angiotensin II, ACE inhibitors promote vasodilation and lower blood pressure. Therefore, while ACE inhibitors effectively decrease hypertension and are widely prescribed, it is essential to recognize that beta-blockers are another common class of drugs used in the treatment of high blood pressure.

Diuretics are a first-line treatment and help lower blood pressure by promoting the excretion of sodium and water from the body, which decreases blood volume. Antibiotics, on the other hand, do not address the underlying mechanisms of hypertension and are not relevant in this context.

Understanding the roles of these different classes of medications is crucial for health professionals in developing effective treatment plans for patients with hypertension.
