• Rifampin: May reduce atorvastatin plasma concentrations.

Drug Interactions that may Decrease Exposure to Atorvastatin Rifampin Clinical Impact: Concomitant administration of atorvastatin with rifampin, an inducer of cytochrome P450 3A4 and inhibitor of OATP1B1, can lead to variable reductions in plasma concentrations of atorvastatin.

Due to the dual interaction mechanism of rifampin, delayed administration of atorvastatin after administration of rifampin has been associated with a significant reduction in atorvastatin plasma concentrations.

Blood pressure should be closely monitored when amlodipine is co-administered with CYP3A inducers.

Intervention: Administer atorvastatin and rifampin simultaneously.
