Candesartanside effects

Most common adverse reactions which caused adult patients to discontinue therapy for: Hypertension were headache (0.6%) and dizziness (0.3%). Heart Failure were hypotension (4.1%), abnormal renal function (6.3%), and hyperkalemia (2.4%).

6.1 Clinical

Studies Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Adult Hypertension Candesartan cilexetil has been evaluated for safety in more than 3600 patients/subjects, including more than 3200 patients treated for hypertension. About 600 of these patients were studied for at least 6 months and about 200 for at least 1 year. In general, treatment with candesartan cilexetil was well tolerated. The overall incidence of adverse events reported with candesartan cilexetil was similar to placebo. The rate of withdrawals due to adverse events in all trials in patients (7510 total) was 3.3% (i.e., 108 of 3260) of patients treated with candesartan cilexetil as monotherapy and 3.5% (i.e., 39 of 1106) of patients treated with placebo. In placebo-controlled trials, discontinuation of therapy due to clinical adverse events occurred in 2.4% (i.e., 57 of 2350) of patients treated with candesartan cilexetil and 3.4% (i.e., 35 of 1027) of patients treated with placebo. The most common reasons for discontinuation of therapy with candesartan cilexetil were headache (0.6%) and dizziness (0.3%). The adverse events that occurred in placebo-controlled clinical trials in at least 1% of patients treated with candesartan cilexetil tablets and at a higher incidence in candesartan cilexetil (n = 2350) than placebo (n = 1027) patients included back pain (3% vs. 2%), dizziness (4% vs. 3%), upper respiratory tract infection (6% vs. 4%), pharyngitis (2% vs. 1%), and rhinitis (2% vs. 1%). Pediatric Hypertension Among children in clinical studies, 1 in 93 children age 1 to < 6 and 3 in 240 age 6 to < 17 experienced worsening renal disease. The association between candesartan and exacerbation of the underlying condition could not be excluded. Heart Failure The adverse event profile of candesartan cilexetil in adult heart failure patients was consistent with the pharmacology of the drug and the health status of the patients. In the CHARM program, comparing candesartan cilexetil in total daily doses up to 32 mg once daily (n=3803) with placebo (n=3796), 21.0% of patients discontinued candesartan cilexetil for adverse events vs. 16.1% of placebo patients.

6.2 Postmarketing

Experience The following adverse reactions were identified during post-approval use of candesartan cilexetil. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following have been very rarely reported in post-marketing experience: Digestive: Abnormal hepatic function and hepatitis.

Hematologic: Neutropenia, leukopenia, and agranulocytosis.

Immunologic: Angioedema.

Metabolic and Nutritional Disorders: Hyperkalemia, hyponatremia.

Respiratory System Disorders: Cough.

Skin and Appendages Disorders: Pruritus, rash and urticaria. Rare reports of rhabdomyolysis have been reported in patients receiving angiotensin II receptor blockers.
