Which of the following medications is primarily used to manage hypertension?

Hydrochlorothiazide is primarily used to manage hypertension because it is classified as a thiazide diuretic. This medication works by promoting the excretion of sodium and water from the kidneys, thereby reducing blood volume and lowering blood pressure. Thiazide diuretics are often considered first-line treatment options for hypertension due to their effectiveness and well-established safety profile.

By decreasing the overall fluid volume, hydrochlorothiazide helps to alleviate the strain on blood vessels, leading to reduced blood pressure levels. It is commonly used in both monotherapy and in combination with other antihypertensive agents to achieve better blood pressure control.

In contrast, the other medications mentioned have different primary indications: Albuterol is a bronchodilator used primarily for asthma and other respiratory conditions, Flovent is an inhaled corticosteroid used to manage asthma and chronic obstructive pulmonary disease (COPD), and Aspirin is primarily used for pain relief and anti-inflammatory effects and also plays a role in cardiovascular protection but is not a primary treatment for hypertension.
