Lovastatin, also known as Mevacor

Drag the structure with the mouse to rotate

Better Known as: Mevacor

  • Marketed By: Merck & Co.
  • Major Indication: Hyperlipidemia & High Cholesterol (Hypercholesterolemia)
  • Drug Class: HMGR Inhibitor or Statin
  • Date of FDA Approval (Patent Expiration): 1991 (2001)
  • 2000 Sales: $520 Million
  • Importance: Was the first HMG-CoA Inhibitor. Statins are so ubiquitous, doctors have even suggested handing them out with fast food. See: the article
  • See Pharmaceutical Drugs for more information about other drugs and disorders

Mechanism of Action

Lovastatin is rapidly hydrolyzed in vivo into its corresponding b-hydroxyacid, which is an inhibitor of HMG-CoA Reductase (HMGR), a highly regulated enzyme responsible for the committed step in cholesterol synthesis. Lovastatin outcompetes HMG-CoA, the substrate of HMGR, in binding to HMGR.[1]
