Indication(s) & Dosage

Candesartan is indicated for the treatment of hypertension in adults and children 1 to <17 years of age. It may be used alone or in combination with other antihypertensive agents.

Candesartan is indicated for the treatment of heart failure (NYHA Class II-IV) in patients with left-ventricular systolic dysfunction (ejection fraction ≤40%) to reduce cardiovascular death and to reduce heart failure hospitalizations. Candesartan also has an added effect on these outcomes when used with an ACE inhibitor.

Renal impairment: For patients with renal impairment or on haemodialysis: Initially, 4 mg once daily.

Special Precautions

Volume or sodium depletion, preexisting renal insufficiency; aortic or mitral valve stenosis, hypertrophic obstructive cardiomyopathy, renal artery stenosis, primary hyperaldosteronism.  Patients with a history of angioedema, urticaria.  Monitor serum potassium levels especially in elderly and renally impaired patients.  Hypotension may occur during major surgery and anaesthesia due to suppression of the renin-angiotensin system.

Adverse Drug Reaction(s)

Dizziness, headache, vertigo, depression, somnolence, fever, back pain, upper respiratory tract infections, 1st dose orthostatic hypotension, rash, diarrhoea, decreased haemoglobin, renal impairment, hepatitis.

Drug Interactions

Prior treatment with diuretics increases risk of excessive hypotension; use a lower initial dose.  Potassium, potassium-sparing diuretics, trimethoprim or potassium supplements may increase risk of hyperkalaemia.  NSAIDs may reduce antihypertensive response and increase risk of hyperkalaemia or acute renal failure.  Excretion of lithium may be reduced; monitor lithium concentration.

Pregnancy Category (FDA)

Category D: There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk.


Oral:  Store at 15-30°C.


Candesartan inhibits the binding of angiotensin II to AT1 receptors in many tissues such as vascular smooth muscles and adrenal gland which leads to vasoconstriction blockade and aldosterone release.  Absorption: Absorbed from the GI tract; peak plasma concentrations after 3-4 hr.  Distribution: Protein-binding: 99%.  Metabolism: Hydrolysed to the active form, candesartan.  Excretion: Via urine and bile; 9 hr.

Gen. MedInfo


Tell your doctor if you are pregnant or plan to become pregnant.  Do not take candesartan if you are pregnant.  If you become pregnant while you are taking candesartan, stop taking candesartan and consult your doctor immediately.  Candesartan may cause death or serious injury to the fetus when taken in the last 6 months of pregnancy.

Why Candesartan is prescribed?

Candesartan is used alone or in combination with other medications to treat high blood pressure.  Candesartan is also used alone or in combination with other medications to treat congestive heart failure.  Candesartan is in a class of medications called angiotensin II receptor antagonists.  It works by blocking the action of certain natural substances that tighten the blood vessels, allowing the blood to flow more smoothly and the heart to pump more efficiently.


Candesartan comes as a tablet to take by mouth.  It is usually taken once or twice a day with or without food.  To help you remember to take candesartan, take it at around the same time every day.  Follow the directions on your prescription label carefully, and ask your Doctor to explain any part you do not understand.  Take candesartan exactly as directed.  Do not take more or less of it or take it more often than prescribed by your doctor.

Your doctor will probably start you on a low dose of candesartan and gradually increase your dose not more than once every 2 weeks.

Candesartan controls high blood pressure but does not cure it.  Your blood pressure may decrease during the first 2 weeks of your treatment, but it may take 4 to 6 weeks for you to notice the full benefit of candesartan.  Continue to take candesartan even if you feel well.  Do not stop taking candesartan without talking to your doctor.

Other uses

Candesartan is also sometimes used to treat diabetic nephropathy.  Talk to your doctor about the risks of using this medication for your condition.

This medication may be prescribed for other uses; ask your Doctor for more information.
