Source: FDA Label • COSETTE • Thiazide Diuretic

How TRIBENZOR Works

Tribenzor utilizes three distinct mechanisms of action to regulate blood pressure. **Amlodipine** inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle, resulting in vasodilation. **Olmesartan medoxomil** is an angiotensin II receptor blocker (ARB) that prevents vasoconstriction and sodium retention by selectively blocking the binding of angiotensin II to the $AT_1$ receptor. **Hydrochlorothiazide** is a thiazide diuretic that promotes the excretion of sodium and chloride in the kidneys, thereby reducing plasma volume and cardiac output. Together, these components provide additive blood pressure reduction compared to the individual agents.
