Atacand HCT contains which active components?

Atacand HCT is a combination medication that contains two active components: candesartan and hydrochlorothiazide (HCTZ). Candesartan is an angiotensin II receptor blocker (ARB) that helps to relax blood vessels, lowering blood pressure, while hydrochlorothiazide is a thiazide diuretic that helps to reduce fluid retention and also contributes to lowering blood pressure. This combination is particularly effective for treating hypertension and is commonly prescribed for patients requiring both an antihypertensive and a diuretic.

The other choices include incorrect combinations of drugs. Olmesartan, Irbesartan, and Bisoprolol are different medications that serve various roles in treating hypertension but are not components of Atacand HCT. Olmesartan and Irbesartan are also ARBs, but they are not used in this specific combination. Bisoprolol is a beta-blocker, which works differently than the components in Atacand HCT, further clarifying the distinct nature of the medication. Thus, the correct combination of candesartan and HCTZ is what makes choice B accurate.
