Description
Azilsartan and chlorthalidone combination is used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can reduce the risk of strokes and heart attacks.
Azilsartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten. As a result, azilsartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Chlorthalidone is a thiazide-like diuretic (water pill). It reduces the amount of water in the body by increasing the flow of urine, which helps lower the blood pressure.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:
