6'-Epipravastatin is a secondary isomeric metabolite of pravastatin. Pravastatin, one of the 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) widely used in the management of hypercholesterolaemia, has unique pharmacokinetic characteristics among the members of this class. The major metabolites of Pravastatin found in plasma, urine and feces are 3′α-isopravastatin, 3′α,5′β-dihydroxy-pravastatin, desacyl-dehydropravastatin, 3′′-hydroxy-pravastatin and 6′-epipravastatin. The major pravastatin metabolites are generated by non-CYP-dependent processes: 3alpha-isopravastatin and metabolite 6-epipravastatin are either formed by acidic degradation of pravastatin in the stomach or by sulfation at the 6’beta-hydroxy group by sulfotransferases, followed by a nucleophilic attack of hydroxy anions at the 3alpha- or 6’alpha-position.
