Drug class: Miscellaneous antihypertensive combinations
What is Exforge HCT?
Exforge HCT contains a combination of amlodipine, hydrochlorothiazide, and valsartan. Amlodipine is a calcium channel blocker that relaxes (widens) blood vessels and improves blood flow.
Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.
Valsartan is an angiotensin II receptor antagonist (sometimes called an ARB) that keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
Exforge HCT is used to treat high blood pressure (hypertension).
Exforge HCT is usually given after other blood pressure medicines have been tried without successful treatment of symptoms.
