Lomitapide , sold under the brand name Juxtapid in the US and Lojuxta in the EU, is a medication used as a lipid-lowering agent for the treatment of familial hypercholesterolemia, developed by Aegerion Pharmaceuticals.

[6] In July 2013, the European Commission approved lomitapide as an adjunct to a low-fat diet and other lipid-lowering medicinal products with or without low density lipoprotein (LDL) apheresis in adults with HoFH.

[2] Lomitapide inhibits the microsomal triglyceride transfer protein (MTP or MTTP) which is necessary for very low-density lipoprotein (VLDL) assembly and secretion in the liver.

[3][7] In December 2012, drug manufacturer Aegerion announced they had been approved by the FDA to as "an adjunct to a low-fat diet and other lipid-lowering treatments...in patients with homozygous familial hypercholesterolemia (HoFH).

"[8][9] In a Phase III study, lomitapide led to elevated aminotransferase levels and fat accumulation in the liver.
