ALTOCOR™
(lovastatin) Extended-Release Tablets

DRUG DESCRIPTION

ALTOCOR™ (Lovastatin) Extended-Release Tablets contain a cholesterol-lowering agent isolated from a strain of Aspergillus terreus. After oral ingestion, lovastatin, which is an inactive lactone, is hydrolyzed to the corresponding β-hydroxyacid form. This is a principal metabolite and inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, which is an early and rate limiting step in the biosynthesis of cholesterol.

Lovastatin is [1 S -[1α(R*),3α,7β,8β(2 S*,4 S*),8aβ]]-1,2,3, 7,8,8a-hexahydro-3,7-dimethyl-8-[2-(tetrahydro-4-hydroxy-6-oxo-2 H -pyran-2-yl)ethyl]-1-naphthalenyl 2-methylbutanoate. The empirical formula of lovastatin is C24H36O5 and its molecular weight is 404.55. Its structural formula is:
