एटोरवास्टेटिन और एल्विटेग्राविर, कोबिसिस्टैट, एमट्रिसिटाबिन और टेनोफोविर का इंटरैक्शन

Lipid-modifying Agents: HMG-CoA Reductase Inhibitors: lovastatin simvastatin ↑ lovastatin ↑ simvastatin Coadministration with lovastatin or simvastatin is contraindicated due to potential for serious reactions such as myopathy including rhabdomyolysis. atorvastatin ↑ atorvastatin Initiate atorvastatin with the lowest starting dose of atorvastatin and titrate…

Do not exceed a dosage of atorvastatin 20 mg daily.

LIPITOR plasma levels can be significantly increased with concomitant administration of inhibitors of CYP3A4 and transporters.

Table 2: Drug Interactions that may Increase the Risk of Myopathy and Rhabdomyolysis with LIPITOR Cyclosporine or Gemfibrozil Clinical Impact: Atorvastatin plasma levels were significantly increased with concomitant administration of LIPITOR and cyclosporine, an inhibitor of CYP3A4 and OATP1B1 [see Clinical Pharmacology (12.3) ] .

Anti-Viral Medications Clinical Impact: Atorvastatin plasma levels were significantly increased with concomitant administration of LIPITOR with many anti-viral medications, which are inhibitors of CYP3A4 and/or transporters (e.g., BCRP, OATP1B1/1B3, P-gp, MRP2, and/or OAT2) [see Clinical Pharmacology (12.3) ] .

Table 3: Drug Interactions that may Decrease Exposure to LIPITOR Rifampin Clinical Impact: Concomitant administration of LIPITOR with rifampin, an inducer of cytochrome P450 3A4 and inhibitor of OATP1B1, can lead to variable reductions in plasma concentrations of atorvastatin.
