Patient Education

Lomitapide


Lomitapide is used along with diet changes (restriction of cholesterol and fat intake) and other treatments to reduce the amount of low-density lipoprotein (LDL) cholesterol ('bad cholesterol'), total cholesterol, and other fatty substances in the blood in people that have homozygous familial hypercholesterolemia (HoFH; an inherited condition in which cholesterol cannot be removed from the body normally). Lomitapide should not be used to decrease cholesterol levels in people who do not have HoFH. Lomitapide is in a class of medications called cholesterol-lowering medications. It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body. Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats may help prevent heart disease, angina (chest pain), strokes, and heart attacks.
