What is Edarbyclor?

Edarbyclor contains a combination of azilsartan and chlorthalidone. Azilsartan is an angiotensin II receptor antagonist. Azilsartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Chlorthalidone is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.

Edarbyclor is used to treat high blood pressure (hypertension). Lowering blood pressure may lower your risk of a stroke or heart attack.
