Often used to lower blood pressure, Ace inhibitors reduce the activity of an enzyme called angiotensin-converting enzyme or ACE for short. The enzyme has a narrowing effect on your blood vessels which increases blood pressure. Ace inhibitors limit this enzyme, allowing your blood vessels to widen, reducing blood pressure and improving blood flow to the heart.
Ace inhibitors are known to reduce blood supply to the kidneys and therefore blood and urine tests might be done for you start taking them. This is to ensure there are no pre-existing problems with your kidneys. The main difference between different types of ACE inhibitors is how long their effects last. There are both short and long acting types. Long acting are taken less frequently, sometimes just once a day whereas short acting ones can be taken up to three times a day. Each drug comes with a range of strengths, it is normal to start on a lower strength and work up as you get used to them.
Side Effects:
1 in 10 people experience a dry, irritating cough from taking ace inhibitors, other side effects include dizziness, tiredness/ weakness and headaches. Most of these side effects should pass after a few days however the dry irritating cough may not. It’s recommended to begin taking ACE inhibitors immediately after a heart attack and in the majority of cases you will continue to take them indefinitely.
