CADUET

AbsorptionAmlodipine: After oral administration of therapeutic doses of amlodipine alone, absorption produces peak plasma concentrations between 6 and 12 hours. Absolute bioavailability has been estimated to be between 64% and 90%. Atorvastatin: After oral administration alone, atorvastatin is rapidly absorbed; maximum plasma concentrations occur within 1 to 2 hours. Extent of absorption increases in proportion to atorvastatin dose. The absolute bioavailability of atorvastatin (parent drug) is ...

14.1 Amlodipine for Hypertension Adult Patients The antihypertensive efficacy of amlodipine has been demonstrated in a total of 15 double-blind, placebo-controlled, randomized studies involving 800 patients on amlodipine and 538 on placebo. Once daily administration produced statistically significant placebo-corrected reductions in supine and standing blood pressures at 24 hours postdose, averaging about 12/6 mmHg in the standing position and 13/7 mmHg in the supine position in patients with mild to moderate hypertension. Maintenance of the blood pressure effect over the 24-hour dosing interva...

The following important adverse reactions are described below and elsewhere in the labeling:

• Myopathy and Rhabdomyolysis [see Warnings and Precautions (5.1) ]
• Immune-Mediated Necrotizing Myopathy [see Warnings and Precautions (5.2) ]
• Hepatic Dysfunction [see Warnings and Precautions (5.3) ]
• Increases in HbA1c and Fasting Serum Glucose Levels [see Warnings and Precautions (5.6) ] Most common adverse reaction to amlodipine is edema which occurred in a dose related manner ( 6.1 ). Most comm...

• Acute liver failure or decompensated cirrhosis [see Warnings and Precautions (5.3) ] .
• Hypersensitivity to amlodipine, atorvastatin or any excipients in ‎CADUET. Hypersensitivity reactions, including anaphylaxis, angioneurotic edema, erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis, have been reported [see Adverse Reactions (6.2) ] .
• Acute liver failure or decomp...

• Myopathy and Rhabdomyolysis: Risk factors include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, concomitant use with certain other drugs, and higher CADUET dosage. Discontinue CADUET if markedly elevated CK levels occur or myopathy is diagnosed or suspected. Temporarily discontinue CADUET in patients experiencing an acute or serious condition at high risk of developing renal failure secondary to rhabdomyolysis. Inform patients of the risk of myopathy and rhabdomyolysi...

7 DRUG INTERACTIONS Data from a drug-drug interaction study involving 10 mg of amlodipine and 80 mg of atorvastatin in healthy subjects indicate that the pharmacokinetics of amlodipine are not altered when the drugs are co-administered. The effect of amlodipine on the pharmacokinetics of atorvastatin showed no effect on the C max : 91% (90% confidence interval: 80 to 103%), but the AUC of atorvast...
