ACE (angiotensin-converting enzyme) inhibitors lower blood pressure. They also treat heart failure and prevent heart attacks and strokes. They block an enzyme that makes blood vessels narrow. As a result, the blood vessels relax and widen. This lowers blood pressure. These medicines also put more water and salt into the urine. This lowers blood pressure too.
These medicines are a good choice for people with diabetes. They don't affect blood sugar levels, and they may protect the kidneys.
Before you start taking this medicine, make sure your doctor knows if you take other medicines, especially water pills (diuretics) or potassium tablets. And tell your doctor if you use a salt substitute. You should not take an ACE inhibitor if you are pregnant or planning to become pregnant.
You may need regular blood tests.
