Nursing implications

Nursing assessment

  • Monitor for signs and symptoms of hepatotoxicity (nausea, vomiting, abdominal pain, fever, jaundice, lethargy, flu-like symptoms, increases in bilirubin ≥2 x upper limit of normal, active liver disease) periodically during therapy. If symptoms occur, discontinue therapy and investigate cause.
  • Lab Test Considerations: Measure ALT, AST, alkaline phosphatase, and total bilirubin prior to starting, prior to each dose increase or monthly during first year, then at least every 3 months and before each dose increase. Measure AST and ALT prior to dose increases. Dose is gradually increased based on safety and tolerability; if patient is taking 5 mg daily for at least 2 wks, may increase to 10 mg daily; if taking 10 mg daily for at least 4 wks, may increase to 20 mg daily; if taking 20 mg daily for at least 4 wks, may increase to 40 mg/day ; if taking 40 mg daily for at least 4 wks, may increase to 60 mg/day.
    • If ALT or AST ≥3 x upper limit of normal and <5 x upper limit of normal, confirm elevation with repeat measure within 1 wk. If confirmed, reduce dose and obtain additional liver-related tests (alkaline phosphatase, total bilirubin, INR). Repeat tests weekly and withhold dosing if signs of abnormal liver function (↑ bilirubin or INR), if transaminase levels ↑ >5 x upper limit of normal, or if transaminase levels do not fall <3 x upper limit of normal within 4 wks. Investigate probable cause. If resuming lomitapide after transaminase resolves to <3 x upper limit of normal, consider ↓ dose and monitor liver tests more frequently. If ALT or AST ≥5 x upper limit of normal, withhold dosing, obtain additional liver tests (alkaline phosphatase, total bilirubin, INR) and investigate probable cause. If resuming lomitapide after transaminase resolves to <3 x upper limit of normal, ↓ dose and monitor liver tests more frequently.
    • Obtain a negative pregnancy test in females with reproductive potential prior to starting therapy.

Potential Nursing Diagnoses

Diarrhea (Side Effects)


  • Lomitapide is only available from health care professionals and pharmacies called the Juxtapid REMS Program because of risk of hepatotoxicity. Information is available at www.JUXTAPIDREMSProgram.com or by calling 1-85-JUXTAPID (1-855-898-2743).
  • Oral: Administer with a glass of water, without food, at least 2 hr after evening meal; food may increase GI adverse reactions. Swallow capsules whole; do not open, crush, dissolve, or chew.
    • If oral contraceptives are used, maximum recommended dose of lomitapide is 30 mg/day.
    • Daily supplements containing 400 international units vitamin E, and at least 200 mg linoleic acid, 210 mg alpha-linolenic acid (ALA), 110 mg eicosapentaenoic acid (EPA), and 80 mg docosahexaenoic acid (DHA) should be included with therapy. Lomitapide reduces absorption of fat-soluble vitamins and serum fatty acids.
    • Colesevelam and cholestyramine must be taken 4 hrs before or 4 hr after lomitapide.

Patient/Family Teaching

  • Instruct patient to take lomitapide as directed, along with daily supplements. Omit messed doses and take next daily dose as scheduled; if >1 wk missed notify health care professional. Do not stop lomitapide without consulting health care professional.
  • Advise patient to avoid grapefruit juice during therapy.
  • Caution patient that alcohol increases risk of liver injury. Limit alcohol to not more than 1 alcoholic drink per day. Advise patient to notify health care professional if signs and symptoms of liver injury occur.
  • Inform patient that GI adverse reactions are common (diarrhea, nausea, vomiting, abdominal pain/discomfort, flatulence, constipation. Strict adherence to a low-fat diet (<20% of total calories from fat) and taking at least 2 hrs after evening meal may minimize reactions.
  • Advise female patient to use effective contraception and avoid breastfeeding during therapy. If oral contraceptive is used, and additional method of contraception should be used. If pregnancy occurs notify health care professional immediately. Encourage pregnant patients to enroll in Global Lomitapide Pregnancy Exposure Registry (PER) by calling 1-877-902-4099.

Evaluation/Desired Outcomes

  • Decrease in LDL cholesterol, total cholesterol, apolipoprotein B, and non HDL cholesterol.

Lomitapide, a microsomal triglyceride transfer protein inhibitor, which is approved for use from 18 years of age, can reduce LDL-C up to 46%.

The same is true for the antilipemic agent lomitapide (Juxtapid).
In addition, as part of Aegerion's post-marketing commitment to both the FDA and the EMA, the Company will conduct an observational cohort study to generate more data on the long-term safety profile of lomitapide, the patterns of use and compliance and the long-term effectiveness of controlling LDL-C levels.
This follows the approval of lomitapide (Juxtapid), a microsomal triglyceride transfer protein (MTP) inhibitor approved in December, to reduce LDL cholesterol, total cholesterol, apolipoprotein B, and non-HDL cholesterol in patients with HoFH.
Aptuit established the chemistry for lomitapide, developed and validated its analytical methods, delivered solid state form control and crystallization R&D, and supplied registration batches of material.
Researchers at the Perelman School of Medicine at the University of Pennsylvania, who led the study, revealed that lomitapide, a first-in-class microsomal triglyceride transfer protein (MTP) inhibitor, substantially and stably reduced LDL cholesterol (the "bad" cholesterol) in patients with the orphan disease homozygous familial hypercholesterolemia (HoFH).
Its lead product, lomitapide in 2011 completed pivotal Phase III clinical trial to treat patients with a rare inherited lipid disorder called homozygous familial hypercholesterolemia, or HoFH.
The single-arm, open label trial is designed to evaluate the efficacy and long-term safety of lomitapide for the treatment of patients with homozygous familial hypercholesterolemia (HoFH).
Lomitapide is designed to treat the disease by limiting secretions of cholesterol and triglycerides from the intestines and liver.
For the 4 patients reported here, all were receiving maximum doses of statin plus ezetimibe with one patient additionally receiving lomitapide 20 mg.
Craig joins Aegerion at a critical time, as we plan for the anticipated approval and launch of lomitapide in 2012," said chief executive officer Marc D.
