What conditions are ACE inhibitors used to treat?

Angiotensin-converting enzyme (ACE) inhibitors are used to treat a number of different conditions:

• High blood pressure (hypertension) - ACE inhibitors usually work well to lower blood pressure.

• Heart failure - ACE inhibitors reduce the strain on the heart by decreasing the amount of fluid pumped around the body. They also help the heart by relaxing blood vessels. This reduces the amount of force needed to eject blood from the heart.

• मधुमेह संबंधी गुर्दा रोग (diabetic nephropathy) - these medicines can help to maintain good kidney function.

• दीर्घकालिक गुर्दा रोग - ACE inhibitors may help to slow the progress of kidney disease.

• After a heart attack (myocardial infarction).

List of ACE inhibitors

They include:

• Captopril.

• Enalapril.

• Fosinopril.

• Imidapril.

• Lisinopril.

• Perindopril.

• Quinapril.

• Ramipril.

• Trandolapril.

Each of these medicines also has various different brand names. Some ACE inhibitor medicines are also part of a combined tablet with a calcium-channel blocker medicine या 'water tablet' (diuretic) medicine.

How do ACE inhibitors work?

ACE inhibitors prevent the body from creating a hormone known as angiotensin II. They do this by blocking (inhibiting) a chemical called angiotensin-converting enzyme.

Angiotensin II has three main effects:

• Tightening (constriction) of blood vessels.

• Re-absorption of water by the kidneys (taking water back into the body).

• Release of the hormone aldosterone which also causes water re-absorption by the kidneys.

Increasing the volume of the blood by adding more water and constricting your blood vessels increases blood pressure.

ACE inhibitors reduce the amount of angiotensin II which causes blood vessels to dilate. The amount of water put back into the blood by the kidneys decreases. These actions reduce blood pressure.

• In high blood pressure (hypertension), ACE inhibitors should help to reduce the blood pressure.

• In heart failure, there may be too much circulating fluid in the blood vessels. ACE inhibitors help to reduce this. They appear to have a protective effect on the heart and slow the progression of the heart failure.

Who cannot take ACE inhibitors?

People who should not take ACE inhibitors include:

• Pregnant and breastfeeding women.

• Those with a known sensitivity to ACE inhibitors.

• Those who have had a severe allergic response to ACE inhibitors in the past - eg, swelling of the lips, eyes or tongue (angio-oedema).

• People with certain types of kidney disease - for example, renal artery stenosis.

A full list of people who should not take ACE inhibitors is included with the leaflet that comes with your medicine. If you are prescribed ACE inhibitors, read this to be sure you are safe to take it.

Side-effects of ACE inhibitors

Side-effects of ACE inhibitors can include:

• Low blood pressure (hypotension).

• चक्कर आना।.

• Persistent dry cough.

• Swelling of the lips, eyes or tongue (angio-oedema).

• Decline in kidney function.

If you experience low blood pressure and dizziness you should report it to your doctor.

A number of medicines may interact with ACE inhibitors. In particular, non-steroidal anti-inflammatory drugs (NSAIDs), 'water tablets' (diuretics) and lithium. Your doctor will normally check what other medicines you take and give further advice about this.

So, make sure your doctor knows of any other medicines that you are taking, including ones that you have bought rather than been prescribed.
