Clinical summary
Indications and usage 1 INDICATIONS AND USAGE Candesartan cilexetil tablets are an angiotensin II receptor blocker (ARB) indicated for: · Treatment of hypertension in adults and children 1 to < 17 years of age, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions ( 1.1 ). · Treatment of heart failure (NYHA class II-IV); candesartan reduces cardiovascular death and heart failure hospitalization ( 1.2 ). 1.1 Hypertension Candesartan cilexetil tablets are indicated for the treatment of hypertension in adults and in children 1 to <17 years of age, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including the class to which this drug principally belongs. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy. Candesartan cilexetil tablets may be used alone or in combination with other antihypertensive agents. 1.2 Heart Failure Candesartan cilexetil tablets are indicated for the treatment of heart failure (NYHA class II-IV) in adults with left ventricular systolic dysfunction (ejection fraction ≤ 40%) to reduce cardiovascular death and to reduce heart failure hospitalizations [see Clinical Studies ( 14.2 )] . Candesartan cilexetil tablets also has an added effect on these outcomes when used with an ACE inhibitor [see Drug Interactions ( 7.4 )] . Dosage and administration 2 DOSAGE AND ADMINISTRATION Starting Dose Target Dose Adult Hypertension ( 2.1 ) 16 mg tablet once daily 8 - 32 mg tablet total daily dose Pediatric Hypertension (1 to 50 kg 8 – 16 mg tablet once daily 50 kg 4 – 32 mg tablet once daily or consider divided dose Adult Heart Failure ( 2.3 ) 4 mg tablet once daily 32 mg tablet once daily 1 1 The target dose is 32 mg once daily, which is achieved by doubling the dose at approximately 2-week intervals, as tolerated by patient. 2.1 Adult Hypertension Dosage must be individualized. Blood pressure response is dose related over the range of 2 to 32 mg. The usual recommended starting dose of candesartan cilexetil tablets are 16 mg once daily when it is used as monotherapy in patients who are not volume depleted. Candesartan cilexetil tablets can be administered once or twice daily with total daily doses ranging from 8 mg to 32 mg. Larger doses do not appear to have a greater effect, and there is relatively little experience with such doses. Most of the antihypertensive effect is present within 2 weeks, and maximal blood pressure reduction is generally obtained within 4 to 6 weeks of treatment with candesartan cilexetil tablets. Use in Hepatic Impairment: Initiate with 8 mg candesartan cilexetil tablets in patients with moderate hepatic insufficiency. Dosing recommendations cannot be provided for patie

[see Warnings and Precautions ( 5.1 ) and Use in Specific Populations ( 8.1 )] Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus [see Warnings and Precautions ( 5.1 ) and Use in Specific Populations ( 8.1 )].

Monitoring
- • 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 Candesartan cilexetil tablets can cause fetal harm when administered to a pregnant woman.
- • 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.
Interaction Notes
- • 7 DRUG INTERACTIONS • Lithium: Increases in serum lithium concentrations and toxicity ( 7 ).
- • • NSAIDs use may lead to increased risk of renal impairment and loss of antihypertensive effect ( 7 ) • Combined inhibition of the renin-angiotensin system: Increased risk of renal impairment, hypotension, and hyperkalemia ( 7 ) 7.1 Agents Increasing Serum Potassium Co-administration of candesartan cilexetil with potassium sparing diuretics, potassium supplements, potassium-containing salt substitutes or other drugs that raise serum potassium levels may result in hyperkalemia.
- • Monitor serum potassium in such patients.
- • 7.2 Lithium Increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with angiotensin II receptor antagonists, including candesartan cilexetil.
