Uses for Lotrel
Amlodipine and benazepril is a combination of medicines that are 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.
Amlodipine is a calcium channel blocker (CCB). It affects the movement of calcium into the cells of the heart and blood vessels. This relaxes the blood vessels and lowers blood pressure. A lower blood pressure will increase the supply of blood and oxygen to the heart.
Benazepril is an angiotensin-converting enzyme (ACE) inhibitor. It works by blocking a substance in the body that causes the blood vessels to tighten. This relaxes the blood vessels and lowers blood pressure.
This medicine is available only with your doctor's prescription.
