What class of drugs is primarily used for hypertension?

Antihypertensives are the class of drugs specifically designed to manage and lower high blood pressure, known as hypertension. These medications work by different mechanisms to relax blood vessels, reduce heart rate, or decrease blood volume, effectively lowering systemic vascular resistance and improving blood flow. Common subcategories of antihypertensives include diuretics, ACE inhibitors, beta-blockers, calcium channel blockers, and angiotensin II receptor blockers, each targeting various aspects of cardiovascular health.

Other classes of drugs mentioned, such as antibiotics, are used to treat bacterial infections and have no impact on blood pressure. Antidepressants are primarily focused on treating mood disorders and may have some side effects that affect blood pressure but are not indicated as primary treatments for hypertension. Antihistamines are typically used for allergies and may have sedative effects, but they do not play a role in managing blood pressure. Hence, antihypertensives are the appropriate choice for treating hypertension specifically.
