The incidence of these abnormalities was 0.2%, 0.2%, 0.6%, and 2.3% for 10, 20, 40, and 80 mg, respectively. One patient in clinical trials developed jaundice. Increases in liver enzyme tests in other patients were not associated with jaundice or other clinical signs or symptoms. Upon dose reduction, drug interruption, or discontinuation, transaminase levels returned to or near pretreatment levels without sequelae. Eighteen of 30 patients with persistent liver enzyme elevations continued treatment with a reduced dose of LIPITOR. Treating to New Targets Study (TNT) In TNT, [see Clinical Studies (14.1) ] 10,001 patients (age range 29-78 years, 19% female; 94% White, 3% Black or African American, 1% Asian, 2% other) with clinically evident CHD we …

7 DRUG INTERACTIONS • See full prescribing information for details regarding concomitant use of LIPITOR with other drugs or grapefruit juice that increase the risk of myopathy and rhabdomyolysis ( 2.5 , 7.1 ). • Rifampin: May reduce atorvastatin plasma concentrations. Administer simultaneously with LIPITOR ( 7.2 ). • Oral Contraceptives: May increase plasma levels of norethindrone and ethinyl estradiol; consider this effect when selecting an oral contraceptive ( 7.3 ). • Digoxin: May increase digoxin plasma levels; monitor patients appropriately ( 7.3 ). 7.1 Drug Interactions that may Increase the Risk of Myopathy and Rhabdomyolysis with LIPITOR LIPITOR is a substrate of CYP3A4 and transporters (e.g., OATP1B1/1B3, P-gp, or BCRP). LIPITOR plasma levels can be significantly increased with concomitant administration of inhibitors of CYP3A4 and transporters. Table 2 includes a list of drugs that may increase exposure to LIPITOR and may increase the risk of myopathy and rhabdomyolysis when used concomitantly and instructions for preventing or managing them [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ] . 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) ] . Gemfibrozil may cause myopathy when given alone. The risk of myopathy and rhabdomyolysis is increased with concomitant use of cyclosporine or gemfibrozil with LIPITOR. Intervention: Concomitant use of cyclosporine or gemfibrozil with LIPITOR is not recommended. 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) ] . Cases of myopathy and rhabdomyolysis have been reported with concomitant use of ledipasvir plus sofosbuvir with LIPITOR. Intervention: • Concomitant use of tipranavir plus ritonavir or glecaprevir plus pibrentasvir with LIPITOR is not recommended. • In patients taking lopinavir plus ritonavir, or simeprevir, consider the risk/benefit of concomitant use with atorvastatin. • In patients taking saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir, fosamprenavir plus ritonavir, elbasvir plus grazoprevir or letermovir, do not exceed LIPITOR 20 mg. • In patients taking nelfinavir, do not exceed LIPITOR 40 mg [see Dosage and Administration (2.5) ]. • Consider the risk/benefit of concomitant use of ledipasvir plus sofosbuvir with LIPITOR. • Monitor all patients for signs and symptoms of myopathy particularly during initiation of therapy and during upward dose titration of either drug. Examples: Tipranavir plus ritonavir, glecaprevir plus pibrentasvir, lopinavir plus ritonavir, simeprevir, saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir, fosamprenavir plus ritonavir, elbasvir plus grazoprevir, letermovir, nelfinavir, and ledipasvir plus sofosbuvir. Select Azole Antifungals or Macrolide Antibiotics Clinical Impact: Atorvastatin plasma levels were significantly increased with concomitant administration of LIPITOR with select azole antifungals or macrolide antibiotics, due to inhibition of CYP3A4 and/or transporters [see Clinical Pharmacology (12.3) ] . Intervention: In patients taking clarithromycin or itraconazole, do not exceed LIPITOR 20 mg [see Dosage and Administration (2.5) ] . Consider the risk/benefit of concomitant use of other azole antifungals or macrolide antibiotics with LIPITOR. Monitor all patients for signs and symptoms of myopathy particularly during initiation of therapy and during upward dose titration of either drug. Examples: Erythromycin, clarithromycin, itraconazole, ketoco …

8 USE IN SPECIFIC POPULATIONS • Pregnancy: May cause fetal harm. ( 8.1 ). • Lactation: Breastfeeding not recommended during treatment with LIPITOR ( 8.2 ). 8.1 Pregnancy Risk Summary Discontinue LIPITOR when pregnancy is recognized. Alternatively, consider the ongoing therapeutic needs of the individual patient. LIPITOR decreases synthesis of cholesterol and possibly other biologically active substances derived from cholesterol; therefore, LIPITOR may cause fetal harm when administered to pregnant patients based on the mechanism of action [see Clinical Pharmacology (12.1) ] . In addition, treatment of hyperlipidemia is not generally necessary during pregnancy. Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hyperlipidemia for most patients. Available data from case series and prospective and retrospective observational cohort studies over decades of use with statins in pregnant women have not identified a drug-associated risk of major congenital malformations. Published data from prospective and retrospective observational cohort studies with LIPITOR use in pregnant women are insufficient to determine if there is a drug-associated risk of miscarriage (see Data ) . In animal reproduction studies, no adverse developmental effects were observed in pregnant rats or rabbits orally administered atorvastatin at doses that resulted in up to 30 and 20 times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 80 mg, based on body surface area (mg/m 2 ). In rats administered atorvastatin during gestation and lactation, decreased postnatal growth and development delay were observed at doses ≥ 6 times the MRHD (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Human Data A Medicaid cohort linkage study of 1,152 statin-exposed pregnant women compared to 886,996 controls did not find a significant teratogenic effect from maternal use of statins in the first trimester of pregnancy, after adjusting for potential confounders – including maternal age, diabetes mellitus, hypertension, obesity, and alcohol and tobacco use – using propensity score-based methods. The relative risk of congenital malformations between the group with statin use and the group with no statin use in the first trimester was 1.07 (95% confidence interval 0.85 to 1.37) after controlling for confounders, particularly pre-existing diabetes mellitus. There were also no statistically significant increases in any of the organ-specific malformations assessed after accounting for confounders. In the majority of pregnancies, statin treatment was initiated prior to pregnancy and was discontinued at some point in the first trimester when pregnancy was identified. Study limitations include reliance on physician coding to define the presence of a malformation, lack of control for certain confounders such as body mass index, use of prescription dispensing as verification for the use of a statin, and lack of information on non-live births. Animal Data Atorvastatin was administered to pregnant rats and rabbits during organogenesis at oral doses up to 300 mg/kg/day and 100 mg/kg/day, respectively. Atorvastatin was not teratogenic in rats at doses up to 300 mg/kg/day or in rabbits at doses up to 100 mg/kg/day. These doses resulted in multiples of about 30 times (rat) or 20 times (rabbit) the human exposure at the MRHD based on surface area (mg/m2). In rats, the maternally toxic dose of 300 mg/kg resulted in increased post-implantation loss and decreased fetal body weight. At the maternally toxic doses of 50 and 100 mg/kg/day in rabbits, there was increased post-implantation loss, and at 100 m …

12.1 Mechanism of Action LIPITOR is a selective, competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme that converts 3-hydroxy-3-methylglutaryl-coenzyme A to mevalonate, a precursor of sterols, including cholesterol. In animal models, LIPITOR lowers plasma cholesterol and lipoprotein levels by inhibiting HMG-CoA reductase and cholesterol synthesis in the liver and by increasing the number of hepatic LDL receptors on the cell surface to enhance uptake and catabolism of LDL; LIPITOR also reduces LDL production and the number of LDL particles.

11 DESCRIPTION LIPITOR (atorvastatin) is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. Atorvastatin calcium is [R-(R*, R*)]-2-(4-fluorophenyl)-ß, δ-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid, calcium salt (2:1) trihydrate. The empirical formula of atorvastatin calcium is (C 33 H 34 FN 2 O 5 ) 2 Ca•3H 2 O and its molecular weight is 1209.42. Its structural formula is: Atorvastatin calcium is a white to off-white crystalline powder that is insoluble in aqueous solutions of pH 4 and below. Atorvastatin calcium is very slightly soluble in distilled water, pH 7.4 phosphate buffer, and acetonitrile; slightly soluble in ethanol; and freely soluble in methanol. LIPITOR tablets for oral use contain atorvastatin 10 mg, 20 mg, 40 mg, or 80 mg (equivalent to 10.36 mg, 20.72 mg, 41.44 mg, or 82.88 mg atorvastatin calcium anhydrous) and the following inactive ingredients: calcium carbonate, USP; candelilla wax, FCC; croscarmellose sodium, NF; hydroxypropyl cellulose, NF; lactose monohydrate, NF; magnesium stearate, NF; microcrystalline cellulose, NF; Opadry White YS-1-7040 (hypromellose, polyethylene glycol, talc, titanium dioxide); polysorbate 80, NF; simethicone emulsion.
