Novel statins: pharmacological and clinical results.

Rosuvastatin (ZD4522) and pitavastatin (NK-104) are novel HMG-CoA reductase inhibitors with a peculiar pharmacological profile. In particular, they show a high potency in decreasing LDL-C and their catabolism is not mediated by the cytochrome P-450 3A4, thus reducing the potential for drug-drug interaction and improving the management of blood cholesterol. As the magnitude of LDL-C reduction is directly associated with the decrease in the incidence of myocardial infarction and mortality for CAD, statins with increased LDL-C lowering potency may ensure the achievement of target LDL-C levels and offer a more aggressive cholesterol control, further improving CAD morbidity and mortality.
