Ava-Enalapril: Uses, Side Effects and Dosage

ABOUT THIS MEDICATION

What the medication is used for:

• reducing high blood pressure

When blood pressure is high, the workload of the heart and arteries increases so that over time, these organs may not function as they should. In turn, this could lead to damage of the "vital organs": brain - heart - kidneys, and result in stroke, heart failure, heart attack, blood vessel disease or kidney disease.

• treating patients with heart failure

Enalapril may also be used to treat patients with heart failure. This is a condition where the heart cannot pump adequate amounts of blood to satisfy the needs of the body.

If your physician has recommended a particular diet, for instance - less salt - follow the diet carefully. This could help your medicine to better control your blood pressure. Your physician may also recommend weight loss. Do follow these suggestions.

What it does:

Enalapril is one of a class of medicines known as angiotensin converting enzyme (ACE) inhibitors. Their action is to lower blood pressure by specifically blocking a naturally occurring substance called angiotensin II. Enalapril allows them to relax and therefore help lower high blood pressure.

This medicine does not cure high blood pressure, but does help control it. So, it is important to continue taking the tablets regularly to keep your blood pressure down. You may have to take high blood pressure medicine for life.

Keep your regular appointments with your physician, even if you feel well. High blood pressure may not be easily recognized by you, because you may not "feel any symptoms"; but your physician can measure your blood pressure very easily, and check how the medicine is controlling it

Read the following information carefully. If you need any explanations, or further information, ask your physician or pharmacist.
