5 WARNINGS AND PRECAUTIONS Observe for signs and symptoms of hypotension (5.3) . Monitor renal function (5.4) and potassium levels (5.5) . 5.1 Fetal Toxicity Pregnancy Category D Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure and death. When pregnancy is detected, discontinue candesartan cilexetil as soon as possible [see USE IN SPECIFIC POPULATIONS ( 8.1 ) ]. Oral doses ≥10 mg of candesartan cilexetil/kg/day administered to pregnant rats during late gestation and continued through lactation were associated with reduced survival and an increased incidence of hydronephrosis in the offspring. The 10-mg/kg/day dose in rats is approximately 2.8 times the maximum recommended daily human dose (MRHD) of 32 mg on a mg/m basis (comparison assumes human body weight of 50 kg). Candesartan cilexetil given to pregnant rabbits at an oral dose of 3 mg/kg/day (approximately 1.7 times the MRHD on a mg/m basis) caused maternal toxicity (decreased body weight and death) but, in surviving dams, had no adverse effects on fetal survival, fetal weight, or external, visceral, or skeletal development. No maternal toxicity or adverse effects on fetal development were observed when oral doses up to 1000 mg of candesartan cilexetil/kg/day (approximately 138 times the MRHD on a mg/m basis) were administered to pregnant mice. Oral doses ≥10 mg of candesartan cilexetil/kg/day administered to pregnant rats during late gestation and continued through lactation were associated with reduced survival and an increased incidence of hydronephrosis in the offspring. The 10-mg/kg/day dose in rats is approximately 2.8 times the maximum recommended daily human dose (MRHD) of 32 mg on a mg/m 2 basis (comparison assumes human body weight of 50 kg). Candesartan cilexetil given to pregnant rabbits at an oral dose of 3 mg/kg/day (approximately 1.7 times the MRHD on a mg/m 2 basis) caused maternal toxicity (decreased body weight and death) but, in surviving dams, had no adverse effects on fetal survival, fetal weight, or external, visceral, or skeletal development. No maternal toxicity or adverse effects on fetal development were observed when oral doses up to 1000 mg of candesartan cilexetil/kg/day (approximately 138 times the MRHD on a mg/m 2 basis) were administered to pregnant mice. 5.2 Morbidity in Infants Children <1 year of age must not receive candesartan cilexetil for hypertension. Drugs that act directly on the renin-angiotensin system (RAS) can have effects on the development of immature kidneys. 5.3 Hypotension Candesartan cilexetil can cause symptomatic hypotension. Symptomatic hypotension is most likely to occur in patients who have been volume and/or salt depleted as a result of prolonged diuretic therapy, dietary salt restriction, dialysis, diarrhea, or vomiting. Patients with symptomatic hypotension may require temporarily reducing the dose of candesartan cilexetil, diuretic or both, and volume repletion. Volume and/or salt depletion should be corrected before initiating therapy with candesartan cilexetil. In the CHARM program (heart failure patients), hypotension was reported in 18.8% of patients on candesartan cilexetil versus 9.8% of patients on placebo. The incidence of hypotension leading to drug discontinuation in candesartan cilexetil-treated patients was 4.1% compared with 2% in placebo-treated patients. In the CHARM-Added program, where candesartan or placebo was given in addition to ACE inhibitors, hypotension was reported in 22.6% of patients treated with candesartan cilexetil versus 13.8% treated with placebo [see DRUG INTERACTIONS ( 7.3 )]. Monitoring of blood pressure is recommended during dose escalation and periodically thereafter. Major Surgery/Anesthesia Hypotension may occur during major surgery and anesthesia in patients treated with angiotensin II receptor antagonists, including candesartan cilexetil, due to blockade of the renin-angiotensin system. Very rarely, hypotension may be severe such that it may warrant the use of intravenous fluids and/or vasopressors. 5.4 Impaired Renal Function Monitor renal function periodically in patients treated with candesartan cilexetil. Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system. Patients whose renal function may depend, in part, on the activity of the renin-angiotensin system (e.g., patient with renal artery stenosis, chronic kidney disease, severe heart failure, or volume depletion) may be at particular risk of developing oliguria, progressive azotemia or acute renal failure when treated with candesartan cilexetil. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function on candesartan cilexetil. In the CHARM program (heart failure patients), the incidence of abnormal renal function (e.g., creatinine increase) was 12.5% in patients treated with candesartan cilexetil versus 6.3% in patients treated with placebo. The incidence of abnormal renal function (e.g., creatinine increase) leading to drug discontinuation in candesartan cilexetil-treated patients was 6.3% compared with 2.9% in placebo-treated patients. In the CHARM-Added program, where candesartan or placebo was given in addition to ACE inhibitors, the incidence of abnormal renal function (e.g., creatinine increase) was 15% in patients treated with candesartan cilexetil versus 9% in patients treated with placebo [see DRUG INTERACTIONS ( 7.3 )]. 5.5 Hyperkalemia Drugs that inhibit the renin-angiotensin system can cause hyperkalemia. Concomitant use of candesartan cilexetil with drugs that may increase potassium levels may increase the risk of hyperkalemia [see DRUG INTERACTIONS ( 7.1 ) ]. Monitor serum potassium periodically. In the CHARM program (heart failure patients), the incidence of hyperkalemia was 6.3% in patients treated with candesartan cilexetil versus 2.1% in patients treated with placebo. The incidence of hyperkalemia leading to drug discontinuation in candesartan cilexetil-treated patients was 2.4% compared with 0.6% in placebo-treated patients. In the CHARM-Added program where candesartan or placebo was given in addition to ACE inhibitors, the incidence of hyperkalemia was 9.5% in patients treated with candesartan cilexetil versus 3.5% in patients treated with placebo [see DRUG INTERACTIONS ( 7 )].

6 ADVERSE REACTIONS Most common adverse reactions which caused adult patients to discontinue therapy for: Hypertension were headache (0.6%) and dizziness (0.3%) (6.1) . Heart Failure were hypotension (4.1%) (5.3) , abnormal renal function (6.3%) (5.4) , and hyperkalemia (2.4%) (5.5) . To report SUSPECTED ADVERSE REACTIONS, contact Sandoz Inc., at 1-800-525-8747 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 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 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% 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.
