Has your doctor prescribed you a Captopril pill? This medicine is often used to treat high blood pressure, heart failure, or to protect the heart after a heart attack. So if you are using this medicine, it is very important to be fully informed about it. Let's talk about it simply today.
Simply put, what is Captopril?
Captopril is a drug that belongs to a class of drugs called ACE inhibitors . Think of the blood vessels in your body as pipes that carry water. If these pipes narrow, more pressure is needed to move the water, right? That's how blood pressure works. An ACE inhibitor relaxes the blood vessels a little. Then the blood can flow more easily, and the pressure decreases.
This is mainly given for high blood pressure and heart disease, but doctors also recommend this medication to reduce kidney damage in some patients, especially those with diabetes.
