Pitavastatin is used together with diet, weight-loss, and exercise to reduce the amount of fatty substances such as low-density lipoprotein (LDL) cholesterol ('bad cholesterol') in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol ('good cholesterol') in adults. Pitavastatin is also used together with diet to decrease the amount of cholesterol and other fatty substances in the blood in teenagers and children 8 years of age and older who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally). Pitavastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). 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 with pitavastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.
