Uses For Lotensin HCT
Benazepril and hydrochlorothiazide is a combination of medicines that 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.
Benazepril is an angiotensin-converting enzyme (ACE) inhibitor. It works by blocking a substance in the body that causes blood vessels to tighten. As a result, benazepril relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Hydrochlorothiazide is a thiazide 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.
