Atorvastatin

Atorvastatin (INN) (IPA: ), marketed under the trade name Lipitor and several others, is a member of the drug class known as statins, used for lowering cholesterol. Atorvastatin inhibits the rate-determining enzyme located in hepatic tissue that produces mevalonate, a small molecule used in the synthesis of cholesterol and other mevalonate derivatives. This lowers the amount of cholesterol produced which in turn lowers the total amount of LDL cholesterol.
