Insights

Lomitapide effectively lowers LDL-C in hypercholesterolemia patients, including those with homozygous familial hypercholesterolemia (HoFH). However, it may cause gastrointestinal issues and impact HDL-C levels.

Area of Science:

  • Cardiovascular Medicine
  • Pharmacology
  • Metabolic Disorders

Background:

  • Hypercholesterolemia, particularly homozygous familial hypercholesterolemia (HoFH), often fails to reach target low-density lipoprotein cholesterol (LDL-C) levels with statin therapy.
  • Novel therapeutic strategies are needed to reduce proatherogenic lipoprotein cholesterol levels.
  • Lomitapide, a microsomal triglyceride transport protein (MTP) inhibitor, is an approved orphan drug for HoFH treatment.

Purpose of the Study:

  • To systematically evaluate the efficacy and safety of lomitapide for managing hypercholesterolemia.
  • To provide clinical guidance on the use of lomitapide.

Main Methods:

  • Systematic literature search of PubMed, Embase, Cochrane Library, and ClinicalTrials.gov for studies published before October 31, 2016.
  • Inclusion of studies involving lomitapide-treated patients, with or without concurrent lipid-lowering therapy.
  • Quality assessment and data extraction by two independent reviewers.

Main Results:

  • Lomitapide significantly reduced LDL-C, total cholesterol, apolipoprotein B, and triglycerides in HoFH patients, with or without other therapies.
  • Favorable effects on LDL-C and triglycerides were also observed in non-HoFH patients with moderate hypercholesterolemia and hypertriglyceridemia.
  • Common adverse events included gastrointestinal disorders, elevated liver transaminases, and hepatic fat accumulation, with long-term use potentially increasing the risk of steatohepatitis and fibrosis. A reduction in high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A-1 (ApoA-1) was noted in both HoFH and non-HoFH patients.

Conclusions:

  • Lomitapide demonstrates efficacy in improving key lipid parameters, excluding HDL-C and ApoA-1, in patients with HoFH and other forms of hypercholesterolemia.
  • Gastrointestinal disturbances are the most frequent adverse events associated with lomitapide treatment.
  • The clinical benefits of lomitapide require careful consideration against its potential long-term adverse effects, particularly hepatic complications.

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Lipid Absorption01:24

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Lipid Catabolism01:25

Lipid Catabolism

Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
