Pravastatin Lactone is a metabolite of pravastatin. Pravastatin is HMG-CoA reductase inhibitor and it is primarily used for the treatment of dyslipidemia and the prevention of cardiovascular disease. Pravastatin and pravastatin-lactone uptake is liver cell specific. Pravastatin-lactone uptake into isolated rat liver cells is carrier mediated. The mutual competitive transport inhibition of bile acids and pravastatin and pravastatin-lactone in sodium-free medium indicates that these compounds share a common transport system. Pravastatin lactone, based on its lipophilicity, showed a high myotoxic potential.
