|statin (stāt'n) Pronunciation Key
Any of a class of drugs that inhibit a key enzyme involved in the synthesis of cholesterol and promote receptor binding of LDL-cholesterol, resulting in decreased levels of serum cholesterol and LDL-cholesterol and increased levels of HDL-cholesterol.
drug that acts to lower cholesterol levels by inhibiting the enzyme HMG-CoA (5-hydroxy-3-methylglutaryl-coenzyme A) reductase, which is required for cholesterol synthesis. Examples of statins include simvastatin, pravastatin, and lovastatin. Statins are generally quite safe, but side effects may include muscle pain and fatigue. A rare side effect called myopathy, characterized by muscle degeneration, has been associated with a mutation in a gene involved in mediating liver uptake of statins.
