Diltiazem is used alone or together with other medicines to treat angina (severe chest pain) or hypertension (high blood pressure). 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. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.

Diltiazem is a calcium channel blocker. It works by affecting the movement of calcium into the cells of the heart and blood vessels. As a result, diltiazem relaxes the blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload.
