Comparative pharmacokinetics of lovastatin, simvastatin and pravastatin in humans.

Twelve healthy male volunteers received single market-image 40-mg oral doses of lovastatin and simvastatin (both lactone prodrugs), or pravastatin (a beta-hydroxyacid) at 1 week intervals in a three-way crossover study to quantify HMG-CoA reductase inhibitors in plasma. Multiple plasma samples were collected up to 24 hours after the dose and assayed for active and total HMG-CoA reductase inhibitors. After equal oral doses, higher plasma concentrations of HMG-CoA reductase inhibitory activity after pravastatin than after either lovastatin of simvastatin (2-3 fold greater area under the concentration-time curve) suggest a greater potential availability of pravastatin-related inhibitory activity to peripheral tissues.
