WebOct 23, 2012 · After absorption in humans, simvastatin undergoes extensive first-pass metabolism in the liver, the primary site of action, with subsequent excretion of drug in bile. The systemic bio-availability of the drug is therefore low: the absolute bioavailability of β-hydroxyacid-simvastatin is less than 5%. Weblovastatin and simvastatin, which are given as prodrugs, all statins are administered in the active hydroxyl acid form (Fig. 1). Once ingested, various other factors affect their absorption, distribution, metabolism, and excretion.
