Which combination is found in Avalide?

Avalide is a combination medication that contains irbesartan and hydrochlorothiazide (HCTZ). This particular pairing is significant because irbesartan is an angiotensin II receptor antagonist, which helps relax blood vessels and lower blood pressure, while hydrochlorothiazide is a diuretic that aids in reducing blood volume by promoting the excretion of sodium and water. Together, these medications work synergistically to effectively manage hypertension.

The other combinations listed do not match the ingredients in Avalide. Losartan, amlodipine, and candesartan are different angiotensin receptor blockers, and while they may be paired with HCTZ in other medications, they are not part of Avalide's formulation. Thus, the correct answer highlights the specific components that define Avalide as a treatment option for high blood pressure.
