BASIC CONCEPTS

1. What does the term “rhabdomyolysis” mean?

ANS:  B

Patients taking the “statin” type of cholesterol-lowering drugs may develop rhabdomyolysis (muscle breakdown). Signs and symptoms of rhabdomyolysis include general muscle soreness, muscle pain and weakness, vomiting, stomach pain, and brown urine. The urine turns brown because small reddish-brown pieces of broken-down muscle are removed from the body through the urine.

2. What problem is usually caused by high blood lipid levels?

ANS:  A

Cholesterol is produced by the liver, and it is in the foods that you eat. However, your body needs only a small amount of cholesterol; too much cholesterol in the bloodstream can deposit in the walls of blood vessels forming plaque that contributes to the development of narrowed arteries such as atherosclerosis and coronary artery disease.

3. What enzyme is inhibited by the “statin” type of lipid-lowering drugs?

ANS:  D

Statins inhibit HMG CoA reductase, an enzyme that controls cholesterol production in the body. They lower blood lipid levels by slowing the production of cholesterol and increasing the ability of the liver to remove LDL cholesterol from the blood. Statins are the most effective group of these drugs for lowering LDL cholesterol.

4. For which patient should statin drugs be avoided?

ANS:  B

Statins should not be given to women who are pregnant, plan to become pregnant, or are breastfeeding. Statins decrease the amount of fat in the body. Fat is essential to brain development in the fetus and infant. When there is not enough fat in the body during pregnancy and infancy, the fetus can suffer poor brain development and mental retardation.
