Clinical Trial Summary

The primary objective of this study is to determine if rifaximin, administered daily has an effect on the cytochrome P450 (CYP) isoenzyme 3A4, by examining any changes in the pharmacokinetics of midazolam (a CYP3A4 substrate), when co-administered.


Clinical Trial Description

This is a single-site, single-arm, open-label, drug-interaction study that examines the effect of rifaximin (RFX), 550 mg 3 times daily (TID; 1650 mg/day), on orally administered (PO) midazolam (MDZ) 2 mg (administered as a 2 mg dose in 1 mL of midazolam HCL Syrup; 2 mg/mL) when dosed for 7 and 14 consecutive days, respectively. ;
