            Warnings

            Contraindications

            Hypersensitivity to amlodipine or atorvastatin

            Active liver disease, or unexplained elevated transminases

            Pregnancy, lactation

            Cautions

            Hypotension with or without syncope is possible (particularly with severe aortic stenosis)

            CHF

            Persistent progressive dermatologic reactions

            Exacerbation of angina and/or MI (during initiation of treatment, after dose increase, or withdrawal of beta blocker)

            Caution in liver impairment

            Heavy alcohol use, history of liver disease, renal failure

            Rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with the atorvastatin

            Myopathy, risk of myopathy increased by coadministration with CYP3A4 inhibiors (eg, fibrates, niacin, cyclosporine, macrolides, azole antifungals); therapy should be discontinued if myopathy diagnosed or suspected

            Co-administration with CYP3A inhibitors (moderate and strong) results in increased systemic exposure to amlodipine and may require dose reduction; monitor for symptoms of hypotension and edema when amlodipine is co-administered with CYP3A inhibitors to determine the need for dose adjustment

            Rare reports of immune-mediated necrotizing myopathy (IMNM), characterized by increased serum creatine kinase that persist despite discontinuing statin

            Withhold or discontinue if myopathy, renal failure, or transaminase levels >3x ULN develops

            Use in patients with recent stroke or TIA: SPARCL study observed higher incidence of hemorrhagic stroke with atorvastatin 80 mg (compared with placebo)

            Increased HbA1c and fasting serum glucose levels reported with HMG-CoA reductase inhibitors

            Clarithromycin, itraconazole, HIV protease inhibitors (saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir, fosamprenavir plus ritonavir) may increase risk of myopathy/rhabdomyolysis; do not exceed 20 mg atorvastatin

            Amlodipine may increase systemic exposure of cyclosporine or tacrolimus when co-administered; frequent monitoring of trough blood levels of cyclosporine and tacrolimus recommended; adjust dose when appropriate

            Pregnancy & Lactation

            Pregnancy Category: X

            Lactation: It is not known whether atorvastatin is excreted into human milk. Because statins have the potential for serious adverse reactions in nursing infants, women taking this drug should not breastfeed their infants

            Pregnancy Categories

            A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA:Information not available.

            Pharmacology

            Mechanism of Action

            Amlodipine: Ca channel blocker: inhibits extracellular Ca ions across the membranes of myocardial cells and vascular smooth muscle cells, without changing serum calcium concentrations, resulting in inhibition of cardiac & vascular smooth muscle contraction, thereby dilating the main coronary and systemic arteries

            Atorvastatin: HMG-CoA reductase inhibitor, inhibits rate-limiting step in cholesterol biosynthesis by competitively inhibiting HMG-CoA reductase

            Pharmacogenomics

            SLCO1B1 (OATP1B1) CC genotype significantly increases AUCs of parent drug and metabolites compared with the CT or TT genotypes

            This polymorphism is proposed to reduced transport into the liver, the main site of statin metabolism and elimination, resulting in elevated plasma concentrations

            SLCO1B1 polymorphism is thought to have a lesser effect on the more hydrophilic statins (eg, rosuvastatin, fluvastatin) compared with more those that are more lipophilic (eg, atorvastatin, pravastatin, simvastatin)

            Other genetic polymorphisms of elimination (eg, CYP450, P-glycoprotein) for each individual drug must also be considered to explain variability for statin clearance among patients that exhibit SCLO1B1 polymorphism

            SLCO1B1 CC genotype is most common in Caucasians and Asians (15%)

            Risk of myopathy is 2.6- to 4.3-fold higher if the C allele is present and 16.9-fold higher in CC homozygotes compared with TT homozygotes
