Patient Education

Trandolapril and Verapamil


The combination of trandolapril and verapamil is used to treat high blood pressure. It is a combination of two medications. It decreases certain chemicals that tighten the blood vessels, so blood flows more smoothly. It also relaxes your blood vessels so your heart does not have to pump as hard. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Blood Pressure Medicines


High blood pressure, also called hypertension, usually has no symptoms. But it can cause serious problems such as stroke, heart failure, heart attack and kidney failure. If you cannot control your high blood pressure through lifestyle changes such as losing weight and reducing sodium in your diet, you may need medicines.

Blood pressure medicines work in different ways to lower blood pressure. Some remove extra fluid and salt from the body. Others slow down the heartbeat or relax and widen blood vessels. Often, two or more medicines work better than one.
