Clinical Practice Guidelines

See individual agents.

Administration: Oral

Administer with or without food.

Dietary Considerations

Before initiation of therapy with atorvastatin, patients should be placed on a standard cholesterol-lowering diet for 3 to 6 months and the diet should be continued during drug therapy.

Red yeast rice contains variable amounts of several compounds that are structurally similar to HMG-CoA reductase inhibitors, primarily monacolin K (or mevinolin) which is structurally identical to lovastatin; concurrent use of red yeast rice with HMG-CoA reductase inhibitors may increase the incidence of adverse and toxic effects (Lapi 2008; Smith 2003).

Contraindications

Hypersensitivity to amlodipine, atorvastatin, or any component of the formulation; active liver disease; unexplained persistent elevations of serum transaminases; pregnancy; breastfeeding

Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to amlodipine, atorvastatin, or to other dihydropyridine calcium channel blockers; concurrent therapy with cyclosporine or glecaprevir/pibrentasvir; severe hypotension (systolic <90 mm Hg).

Warnings/Precautions

Concerns related to adverse effects:

• Angina/myocardial infarction: Increased angina and/or myocardial infarction (MI) has occurred with initiation or dosage titration of dihydropyridine calcium channel blockers. Reflex tachycardia may occur resulting in angina and/or MI in patients with obstructive coronary disease especially in the absence of concurrent beta-blockade.

• Diabetes mellitus: Increases in HbA1c and fasting blood glucose have been reported.

• Hepatotoxicity: Persistent elevations in serum transaminases have been reported; upon dose reduction, drug interruption, or discontinuation, transaminase levels returned to or near pretreatment levels. Postmarketing reports of fatal and nonfatal hepatic failure with atorvastatin have been reported and are rare. If serious hepatotoxicity with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment, interrupt therapy promptly. If an alternate etiology is not identified, do not restart atorvastatin. Liver enzyme tests should be obtained at baseline and as clinically indicated if signs/symptoms of liver injury occur. Ethanol may enhance the potential of adverse hepatic effects; instruct patients to avoid excessive ethanol consumption.

• Hypotension/syncope: Symptomatic hypotension with or without syncope can rarely occur with amlodipine; blood pressure must be lowered at a rate appropriate for the patient's clinical condition.

• Myopathy/rhabdomyolysis: Rhabdomyolysis with acute renal failure secondary to myoglobinuria and/or myopathy has been reported; patients should be monitored closely. This risk is dose-related and is increased with concurrent use of CYP3A4 inhibitors; if concurrent use is warranted, consider lower starting and maintenance doses of atorvastatin. Use caution in patients with inadequately treated hypothyroidism and those taking other drugs associated with myopathy (eg, colchicine); these patients are predisposed to myopathy. Immune-mediated necrotizing myopathy associated with HMG-CoA reductase inhibitors use has also been reported. Patients should be instructed to report unexplained muscle pain, tenderness, weakness, or brown urine, particularly if accompanied by malaise or fever. Discontinue therapy if markedly elevated CPK levels occur or if myopathy is suspected/diagnosed.

• Peripheral edema: The most common side effect of amlodipine is peripheral edema (dose dependent); occurs within 2 to 3 weeks of starting therapy.

Disease-related concerns:

• Aortic stenosis: Use amlodipine with extreme caution in patients with severe aortic stenosis; may reduce coronary perfusion resulting in ischemia.

• Hepatic impairment and/or ethanol use: Use atorvastatin with caution in patients who consume large amounts of ethanol or have a history of liver disease; use is contraindicated in patients with active liver disease or unexplained persistent elevations of serum transaminases. Use amlodipine with caution in patients with hepatic impairment; may require lower starting dose; titrate slowly in patients with severe hepatic impairment.

• Hypertrophic cardiomyopathy with outflow tract obstruction: Use amlodipine with caution in patients with hypertrophic cardiomyopathy and outflow tract obstruction since reduction in afterload may worsen symptoms associated with this condition (ACCF/AHA [Gersh 2011]).

• Renal impairment: Use atorvastatin with caution in patients with renal impairment; these patients are predisposed to myopathy.

• Stroke: Patients with recent stroke or transient ischemic attack receiving long-term therapy with high-dose (ie, 80 mg/day) atorvastatin may be at increased risk for hemorrhagic stroke (SPARCL Investigators, 2006). A subsequent post-hoc analysis demonstrated that patients with lacunar or hemorrhagic stroke may be at higher risk of hemorrhagic stroke; however, this finding was determined to be hypothesis generating. The overall benefit of treatment with atorvastatin (ie, reduced risk of stroke and cardiovascular events) in this population seems to outweigh the increased risk of hemorrhagic stroke if one truly exists (Goldstein 2008).

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information

Special populations:

• Elderly: Use atorvastatin with caution in patients with advanced age, these patients are predisposed to myopathy.

• Surgical patients: The manufacturer recommends temporary discontinuation for elective major surgery, acute medical or surgical conditions, or in any patient experiencing an acute, serious condition suggestive of a myopathy or having a risk factor predisposing to rhabdomyolysis (eg, sepsis, hypotension, trauma, uncontrolled seizures, severe metabolic, endocrine, or electrolyte disorders). Based on current research and clinical guidelines, HMG-CoA reductase inhibitors should be continued in the perioperative period for noncardiac and cardiac surgery (ACC/AHA [Fleisher 2014]; ACC/AHA [Hillis 2011]). Perioperative discontinuation of statin therapy is associated with an increased risk of cardiac morbidity and mortality.

Other warnings/precautions:

• Appropriate use: Secondary causes of hyperlipidemia should be ruled out prior to therapy with atorvastatin. Atorvastatin has not been studied when the primary lipid abnormality is chylomicron elevation (Fredrickson types I and V).

• Titration: Dosage titration of amlodipine should occur after 7 to 14 days on a given dose.

Reproductive Considerations

Effective contraception should be used during treatment in females of reproductive potential.

Pregnancy Considerations

Rifamycin Derivatives: May decrease the serum concentration of Calcium Channel Blockers. This primarily affects oral forms of calcium channel blockers. Management: The labeling for some US and Canadian calcium channel blockers contraindicate use with rifampin, however recommendations vary. Consult appropriate labeling. Risk D: Consider therapy modification

Rifamycin Derivatives: May decrease the serum concentration of HMG-CoA Reductase Inhibitors (Statins). Management: Consider use of noninteracting antilipemic agents (note: pitavastatin concentrations may increase with rifamycin treatment). Monitor for altered HMG-CoA reductase inhibitor effects. Rifabutin and fluvastatin, or possibly pravastatin, may pose lower risk. Risk D: Consider therapy modification

Rupatadine: May enhance the adverse/toxic effect of HMG-CoA Reductase Inhibitors (Statins). Specifically, the risk for increased CPK and/or other muscle toxicities may be increased. Risk C: Monitor therapy

Sarilumab: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Risk C: Monitor therapy

Siltuximab: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Risk C: Monitor therapy

Simeprevir: May increase the serum concentration of AtorvaSTATin. Management: The maximum atorvastatin dose should not exceed 40 mg/day with concurrent use of simeprevir, and use of the lowest necessary atorvastatin dose is recommended. Risk D: Consider therapy modification

Simvastatin: AmLODIPine may increase the serum concentration of Simvastatin. Management: Dose of simvastatin should not exceed 20 mg daily if coadministering with levamlodipine or amlodipine. If coadministering with simvastatin and amlodipine, close laboratory and clincal monitoring for signs and symptoms of rhabdomyolysis is warranted. Risk D: Consider therapy modification

Sincalide: Drugs that Affect Gallbladder Function may diminish the therapeutic effect of Sincalide. Management: Consider discontinuing drugs that may affect gallbladder motility prior to the use of sincalide to stimulate gallbladder contraction. Risk D: Consider therapy modification

Spironolactone: AtorvaSTATin may enhance the adverse/toxic effect of Spironolactone. Specifically, there is a theoretical potential for enhanced effects on reducing endogenous steroid activity. Risk C: Monitor therapy

St John's Wort: May increase the metabolism of HMG-CoA Reductase Inhibitors (Statins). Management: Consider avoiding the concomitant administration of St Johns Wort with interacting HMG-CoA reductase inhibitors in order to avoid the potential for decreased antilipemic effects. Monitor for decreased effects during concomitant therapy. Risk D: Consider therapy modification

Stiripentol: May increase the serum concentration of CYP3A4 Substrates (High risk with Inhibitors). Management: Use of stiripentol with CYP3A4 substrates that are considered to have a narrow therapeutic index should be avoided due to the increased risk for adverse effects and toxicity. Any CYP3A4 substrate used with stiripentol requires closer monitoring. Risk D: Consider therapy modification

Tacrolimus (Systemic): Calcium Channel Blockers (Dihydropyridine) may increase the serum concentration of Tacrolimus (Systemic). Risk C: Monitor therapy

Talazoparib: AtorvaSTATin may increase the serum concentration of Talazoparib. Risk C: Monitor therapy

Telithromycin: May increase the serum concentration of AtorvaSTATin. Management: Consider limiting atorvastatin to a max (adult) dose of 20 mg/day when used with telithromycin. Although not a specific recommendation in atorvastatin labeling, this is consistent with dosing for other strong CYP3A4 inhibitors, including clarithromycin. Risk D: Consider therapy modification

Teriflunomide: May increase the serum concentration of OATP1B1/1B3 (SLCO1B1/1B3) Substrates. Risk C: Monitor therapy

Ticagrelor: May increase the serum concentration of AtorvaSTATin. Risk C: Monitor therapy

Tipranavir: May increase the serum concentration of AtorvaSTATin. Risk X: Avoid combination

Tocilizumab: May decrease the serum concentration of CYP3A4 Substrates (High risk with Inducers). Risk C: Monitor therapy

Tolvaptan: May increase the serum concentration of OATP1B1/1B3 (SLCO1B1/1B3) Substrates. Management: Avoid concomitant use of OATP1B1/1B3 substrates in patients receiving the Jynarque brand of tolvaptant. Concentrations and effects of the OATP1B1/1B3 substrate would be expected to increase with combined use. Risk D: Consider therapy modification

Trabectedin: HMG-CoA Reductase Inhibitors (Statins) may enhance the myopathic (rhabdomyolysis) effect of Trabectedin. Risk C: Monitor therapy

Triazolam: CYP3A4 Inhibitors (Weak) may increase the serum concentration of Triazolam. Management: Consider triazolam dose reduction in patients receiving concomitant weak CYP3A4 inhibitors. Risk D: Consider therapy modification

Ubrogepant: CYP3A4 Inhibitors (Weak) may increase the serum concentration of Ubrogepant. Management: In patients taking weak CYP3A4 inhibitors, the initial and second dose (if needed) of ubrogepant should be limited to 50 mg. Risk D: Consider therapy modification

Velpatasvir: May increase the serum concentration of AtorvaSTATin. Risk C: Monitor therapy

Verapamil: AtorvaSTATin may increase the serum concentration of Verapamil. Verapamil may increase the serum concentration of AtorvaSTATin. Management: Consider using lower atorvastatin doses when used together with verapamil. Risk D: Consider therapy modification

Voriconazole: May increase the serum concentration of AtorvaSTATin. Management: Monitor for toxic effects of atorvastatin (e.g., myalgia, rhabdomyolysis, liver function test abnormalities) during concomitant treatment, and reduce atorvastatin dose when possible. Consider use of fluva-, rosuva-, pitava-, or pravastatin when possible. Risk D: Consider therapy modification

Voxilaprevir: May increase the serum concentration of HMG-CoA Reductase Inhibitors (Statins). Management: Use the lowest statin dose possible if combined with voxilaprevir and monitor patients for increased statin effects/toxicities. Avoid concomitant use of voxilaprevir with rosuvastatin or pitavastatin, and limit pravastatin doses to 40 mg daily. Risk D: Consider therapy modification

Yohimbine: May diminish the antihypertensive effect of Antihypertensive Agents. Risk C: Monitor therapy

2013 ACC/AHA Blood Cholesterol Guideline recommendations (ACC/AHA [Stone 2013]):

Lipid panel (total cholesterol, HDL, LDL, triglycerides): Baseline lipid panel; fasting lipid profile within 4 to 12 weeks after initiation or dose adjustment and every 3 to 12 months (as clinically indicated) thereafter. If 2 consecutive LDL levels are <40 mg/dL, consider decreasing the dose.

Hepatic transaminase levels: Baseline measurement of hepatic transaminase levels (ie, ALT); measure hepatic function if symptoms suggest hepatotoxicity (eg, unusual fatigue or weakness, loss of appetite, abdominal pain, dark-colored urine or yellowing of skin or sclera) during therapy.

CPK: CPK should not be routinely measured. Baseline CPK measurement is reasonable for some individuals (eg, family history of statin intolerance or muscle disease, clinical presentation, concomitant drug therapy that may increase risk of myopathy). May measure CPK in any patient with symptoms suggestive of myopathy (pain, tenderness, stiffness, cramping, weakness, or generalized fatigue).

Evaluate for new-onset diabetes mellitus during therapy; if diabetes develops, continue statin therapy and encourage adherence to a heart-healthy diet, physical activity, a healthy body weight, and tobacco cessation.

If patient develops a confusional state or memory impairment, may evaluate patient for nonstatin causes (eg, exposure to other drugs), systemic and neuropsychiatric causes, and the possibility of adverse effects associated with statin therapy.

Manufacturer's labeling: Liver enzyme tests at baseline and repeated when clinically indicated. Measure CPK when myopathy is being considered or may measure CPK periodically in high risk patients (eg, drug-drug interaction). Upon initiation or titration, lipid panel should be analyzed within 2 to 4 weeks.

Advanced Practitioners Physical Assessment/Monitoring

Rule out secondary causes of hyperlipidemia prior to initiation. Assess blood pressure and heart rate. Assess other medicines patient may be taking, alternate therapy or dosage adjustments may be needed. Obtain liver enzyme tests and CPK (when myopathy is considered or in high-risk patients). Follow-up with lipid panel within 2 to 4 weeks of initiation or titration. Adjust dosing appropriately in patients with recent history of stroke.

Nursing Physical Assessment/Monitoring

Check ordered labs and report any abnormalities. Check blood pressure and heart rate as ordered. Monitor for and educate patient to report signs and symptoms of myopathy (muscle pain, weakness, fatigue). Consider dietary assessment and plan for teaching.

Mechanism of Action

Amlodipine: Inhibits calcium ion from entering the “slow channels” or select voltage-sensitive areas of vascular smooth muscle and myocardium during depolarization, producing a relaxation of coronary vascular smooth muscle and coronary vasodilation; increases myocardial oxygen delivery in patients with vasospastic angina. Amlodipine directly acts on vascular smooth muscle to produce peripheral arterial vasodilation reducing peripheral vascular resistance and blood pressure.

Atorvastatin: Inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the rate limiting enzyme in cholesterol synthesis (reduces the production of mevalonic acid from HMG-CoA); this then results in a compensatory increase in the expression of LDL receptors on hepatocyte membranes and a stimulation of LDL catabolism. In addition to the ability of HMG-CoA reductase inhibitors to decrease levels of high-sensitivity C-reactive protein (hsCRP), they also possess pleiotropic properties including improved endothelial function, reduced inflammation at the site of the coronary plaque, inhibition of platelet aggregation, and anticoagulant effects (de Denus 2002; Ray 2005).
