ir plus ritonavir, fosamprenavir, or fosamprenavir plus ritonavir, the dose of LIPTRUZET should not exceed 10/20 mg and should be used with caution [see Warnings and Precautions (5.1) and Dosage and Administration (2.3)]. In patients taking the HIV protease inhibitor nelfinavir or the hepatitis C protease inhibitor boceprevir, the dose of LIPTRUZET should not exceed 10/40 mg daily and close clinical monitoring is recommended.
Itraconazole: Atorvastatin AUC was significantly increased with concomitant administration of atorvastatin 40 mg and itraconazole 200 mg [see Clinical Pharmacology (12.3)]. Therefore, in patients taking itraconazole, do not use a LIPTRUZET dose that exceeds 10/20 mg [see Warnings and Precautions (5.1) and Dosage and Administration (2.3)].
7.2 CyclosporineAtorvastatin and atorvastatin-metabolites are substrates of the OATP1B1 transporter. Inhibitors of the OATP1B1 (e.g., cyclosporine) can increase the bioavailability of atorvastatin. Atorvastatin AUC was significantly increased with concomitant administration of atorvastatin 10 mg and cyclosporine 5.2 mg/kg/day compared to that of atorvastatin alone [see Clinical Pharmacology (12.3)].
In addition, ezetimibe and cyclosporine used concomitantly can increase exposure to both ezetimibe and cyclosporine. The degree of increase in ezetimibe exposure may be greater in patients with severe renal impairment.
The coadministration of LIPTRUZET with cyclosporine should be avoided [see Warnings and Precautions (5.1)].
7.3 Grapefruit JuiceGrapefruit juice contains one or more components that inhibit CYP3A4 and can increase plasma concentrations of atorvastatin, especially with excessive grapefruit juice consumption (>1.2 liters per day).
7.4 GemfibrozilDue to an increased risk of myopathy/rhabdomyolysis when HMG-CoA reductase inhibitors are coadministered with gemfibrozil, concomitant administration of LIPTRUZET with gemfibrozil should be avoided [see Warnings and Precautions (5.1)].
7.5 Fenofibrates (e.g., fenofibrate and fenofibric acid)Because it is known that the risk of myopathy during treatment with HMG-CoA reductase inhibitors is increased with concurrent administration of fenofibrates, LIPTRUZET should be administered with caution when used concomitantly with a fenofibrate [see Warnings and Precautions (5.1)].
Fenofibrates may increase cholesterol excretion into the bile, leading to cholelithiasis. If cholelithiasis is suspected in a patient receiving LIPTRUZET and a fenofibrate, gallbladder studies are indicated and alternative lipid-lowering therapy should be considered [see the product labeling for fenofibrate and fenofibric acid].
7.6 NiacinThe risk of skeletal muscle effects may be enhanced when LIPTRUZET is used in combination with niacin; a reduction in LIPTRUZET dosage should be considered in this setting [see Warnings and Precautions (5.1)].
7.7 DigoxinWhen multiple doses of atorvastatin and digoxin were coadministered, steady state plasma digoxin concentrations increased by approximately 20%. Patients taking digoxin should be monitored appropriately.
7.8 Oral ContraceptivesCoadministration of atorvastatin and an oral contraceptive increased AUC values for norethindrone and ethinyl estradiol [see Clinical Pharmacology (12.3)]. These increases should be considered when selecting an oral contraceptive for a woman taking LIPTRUZET.
