Candesartan belongs to the group of vasodilator drugs known as angiotensin II blockers and is used to treat hypertension (high blood pressure) and heart failure (inability of the heart muscle to cope with its workload). Candesartan works by blocking the action of angiotensin II (a hormone that constricts blood vessels). This relaxes the blood vessels, thereby lowering blood pressure and easing the heart’s workload.
Unlike ACE inhibitors, candesartan does not cause a persistent dry cough and may be a useful alternative for people who have to discontinue treatment with an ACE inhibitor for this reason.

POSSIBLE ADVERSE EFFECTS
Adverse effects of candesartan are usually mild and transient. Common effects include dizziness, headache, flushing, and nausea. More rarely, there may be muscle or joint pain. If you develop jaundice or swelling of the face or lips, stop taking the drug and consult your doctor immediately.
ACE inhibitors (e.g. enalapril, captopril, lisinopril, or ramipril) may increase potassium levels when taken with candesartan.
Diuretics There is a risk of a sudden fall in blood pressure if these drugs are taken when candesartan treatment is started. They may also affect sodium and potassium levels in the blood.
NSAIDs (e.g. diclofenac or ibuprofen) may reduce candesartan’s effectiveness.
Lithium Levels of this drug may be increased when it is combined with candesartan, leading to toxicity.
Ciclosporin may increase potassium levels when combined with candesartan.
Potassium salts may increase risk of high potassium levels with candesartan.

No special problems.
Monitoring Periodic checks on blood potassium levels and kidney function may be performed.
