Zocor Indication:

For the treatment of hypercholesterolemia.

Zocor Mechanism Of Action:

The 6-membered lactone ring of simvastatin is hydrolyzed in vivo to generate mevinolinic acid, an active metabolite structurally similar to HMG-CoA (hydroxymethylglutaryl CoA). Once hydrolyzed, simvastatin competes with HMG-CoA for HMG-CoA reductase, a hepatic microsomal enzyme. Interference with the activity of this enzyme reduces the quantity of mevalonic acid, a precursor of cholesterol.

Absorption of simvastatin, estimated relative to an intravenous reference dose, in each of two animal species tested, averaged about 85% of an oral dose. In animal studies, after oral dosing, simvastatin achieved substantially higher concentrations in the liver than in non-target tissues.

Toxicity (Overdose):

Not Available

Protein Binding:

Both simvastatin and its b-hydroxyacid metabolite are highly bound (approximately 95%) to human plasma proteins.


Hepatic, simvastatin is a substrate for CYP3A4.
