• ↑risk of cholelithiasis with fenofibrates.
• Concurrent use with cholestyramine may ↓ effectiveness of ezetimibe.
• May ↑ levels of norethindrone and ethinyl estradiol.
• Rifampin should be taken simultaneously to avoid multiple effects on blood levels.
• May ↑ effects of warfarin.
• May slightly ↑serum digoxin levels.

Drug-Food:

• Grapefruit juice↑ levels and risk of rhabdomyolysis (avoid >1 qt/day).

• Tablets: ezetimibe 10 mg/atorvastatin10 mg; ezetimibe 10 mg/atorvastatin 20 mg; ezetimibe 10 mg/atorvastatin 40 mg; ezetimibe 10 mg/atorvastatin 80 mg;

• PO (Adults): Starting dose — ezetimibe 10 mg/atorvastatin 10 mg or ezetimibe 10 mg/atorvastatin 20 mg; starting dose in patients requiring >55% decrease in LDL-C — ezetimibe 10 mg/atorvastatin 40 mg; concurrent use of clarithromycin, darunavir/ritonavir, fosamprenavir, fosamprenavir/ritonavir, itraconazole, saquinavir/ritonavir — daily dose should not exceed ezetimibe 10 mg/atorvastatin 20 mg); concurrent use of nelfinavir or bocepravir — (daily dose should not exceed ezetimibe 10 mg/atorvastatin 40 mg).

Liptruzet

• Atorvastatin — Inhibits 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, an enzyme which is responsible for catalyzing an early step in the synthesis of cholesterol.
• Ezetimibe — Inhibits absorption of cholesterol in the small intestine.

• Lowering of lipids with decreased progression of atherosclerosis.

Therapeutic Classification: lipid-lowering agents

Pharmacologic Classification: hmg coa reductase inhibitors, cholesterol absorption inhibitors

Absorption: Atorvastatin — rapidly absorbed but undergoes extensive gastrointestinal and hepatic metabolism resulting in 14% bioavailability (30% for lipid-lowering activity). Ezetimibe — following absorption, rapidly converted to the active metabolite ezetimibe-glucaronide. Bioavailability is variable.

Distribution: Atorvastatin — probably enters breast milk.

Protein Binding: Atorvastatin — 98%.

Metabolism/Excretion: Atorvastatin — extensively metabolized by the liver, most during first pass; excreted in bile and feces. <2% excreted unchanged by the kidneys. 2 metabolites have lipid-lowering activity. Ezetimibe — undergoes enterhepatic recycling, mostly eliminated in feces, minimal renal excretion.

Half-life: Atorvastatin — 14 hr (lipid-lowering activity due to atorvastatin and its metabolites — 20–30 hr). Ezetimibe — 22 hr.

(cholesterol-lowering effect)

†Following discontinuation.

• Instruct patient to take medication as directed. If a dose is missed, omit and resume usual schedule with next dose. Do not double up on missed doses. Advise patient to avoid drinking more than one quart of grapefruit juice or 2 glasses of alcohol per day during therapy. Medication helps control but does not cure elevated serum cholesterol levels. Instruct patient to read Patient Leaflet prior to starting therapy and with each Rx refill in case of changes.
• Advise patient that this medication should be used in conjunction with diet restrictions (fat, cholesterol, carbohydrates, alcohol), exercise, and cessation of smoking. Atorvastatin/ezetimibe does not assist with weight loss.
• Instruct patient to notify health care professional promptly if unexplained muscle pain, tenderness, or weakness occurs, especially if accompanied by fever or malaise.Also notify health care professional if signs of liver problems (feeling tired or weak; loss of appetite; upper belly pain; dark urine; or yellowing of skin or whites of eyes).
• Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult health care professional before taking any other Rx, OTC, or herbal products.
• Advise patient to notify health care professional of medication regimen prior to treatment or surgery.
• Instruct female patients to notify health care professional promptly if pregnancy is planned or suspected or if breastfeeding. HMG-CoA reductase inhibitors are contraindicated in pregnancy.
