Ace Inhibitors – Pharmacology for Nurses

Ace Inhibitors are also known as Angiotensin-converting enzyme is used to treat conditions such as:

  • Hypertension
  • Migraines
  • Coronary artery disease
  • Heart failure (CHF)
  • Heart Attacks (MI)
  • Some Chronic renal failures
  • Diabetes
  • Scleroderma

For exam questions on Ace inhibitors, remember that it is used to:


  • lower the blood pressure
  • Increase cardiac output by dilating vessels
  • Reduce afterload

Ace inhibitors relax blood vessels by preventing an enzyme in the patients body from producing a substance called angiotensin II.  Angiotensin II affects the cardiovascular system by narrowing blood vessels and releasing hormones that increase blood pressure. The narrowing of the blood vessels causes hypertension and this makes the cardiac muscle (heart) work harder. Therefore, Ace inhibitors stop the constriction of the blood vessels, lowering the blood pressure and decreases the workload of the heart.

It is important to note that angiotensin II can also promote growth in a negative way, meaning that it can increase the size or thickness of cardiovascular structures that can lead to hypertrophy of the heart.
