Does rifampin greatly reduce plasma simvastatin and simvastatin acid concentrations?
Rifampin greatly decreases the plasma concentrations of simvastatin and simvastatin acid. Because the elimination half-life of simvastatin was not affected by rifampin, induction of the CYP3A4-mediated first-pass metabolism of simvastatin in the intestine and the liver probably explains this interaction. Concomitant use of potent inducers of CYP3A4 can lead to a considerably reduced cholesterol-lowering efficacy of simvastatin.
The results suggest that expression of SAK followed by activation of plg alleviates the course of S. aureus sepsis.
