Patient Education

Nimodipine


Nimodipine is used to decrease brain damage that may be caused by a subarachnoid hemorrhage (bleeding in the space surrounding the brain that occurs when a weakened blood vessel in the brain bursts). Nimodipine is in a class of medications called calcium channel blockers. It works by relaxing blood vessels in the brain to allow more blood to flow to damaged areas.

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.
