ACE inhibitors (angiotensin-converting enzyme inhibitors) are medications that are used to treat high blood pressure (hypertension) and heart failure. They work by blocking the action of an enzyme called angiotensin-converting enzyme (ACE), which is responsible for converting angiotensin I to angiotensin II. Angiotensin II is a hormone that constricts blood vessels and increases blood pressure. By blocking the action of ACE, ACE inhibitors can help relax the blood vessels and lower blood pressure.

Some examples of ACE inhibitors include:

  • Lisinopril
  • Ramipril
  • Enalapril
  • Captopril

The cost of ACE inhibitors can vary depending on the specific medication and the dosage. In the United States, the average cost of a month’s supply of lisinopril (a common ACE inhibitor) is around $15-$20. However, prices may be higher or lower depending on the pharmacy and the patient’s insurance coverage.

ACE inhibitors are usually taken once or twice a day, depending on the specific medication and the individual’s needs. The dosage is typically adjusted based on the patient’s blood pressure and other factors, such as age, kidney function, and any other medical conditions.

Like all medications, ACE inhibitors can cause side effects, although they are generally well tolerated. Common side effects of ACE inhibitors include:

  • Dry cough
  • Dizziness
  • Headache
  • Weakness
  • Nausea

Less common side effects may include:

  • Rash
  • Chest pain
  • Rapid heartbeat
  • Swelling of the face, lips, tongue, or throat (which may be a sign of an allergic reaction)

It is important to report any side effects to a healthcare provider. In some cases, the dosage may need to be adjusted or the medication may need to be discontinued.
