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.
