Which of the following is the combination in Tribenzor?

Tribenzor is a combination medication that includes olmesartan, amlodipine, and hydrochlorothiazide (HCTZ). The combination works to manage high blood pressure through different mechanisms: olmesartan is an angiotensin II receptor blocker (ARB) that helps to relax blood vessels, allowing blood to flow more easily; amlodipine is a calcium channel blocker that also reduces blood pressure by relaxing blood vessels; and hydrochlorothiazide is a diuretic that helps to prevent the body from absorbing too much salt, which can cause fluid retention. By combining these three medications, Tribenzor effectively addresses hypertension from multiple angles, leading to improved blood pressure control.

The other options mention different combinations of medications that are used to manage hypertension but do not represent the specific formulation of Tribenzor. This clear distinction helps to understand the unique composition of Tribenzor and its role in treating high blood pressure.
