Dose/Conc.(herb) : 60 mg four times daily (standardized to 24% flavones glycoside and 6% terpene lactones)
Duration : 28 days
Type of interaction : Pharmacokinetics
Interaction with drug : Midazolam*/Versed/Dormicum
Dose/Conc.(drug) : 8 mg
Result : Negative
Remark :
Note : Twelve healthy volunteers were randomly assigned to receive each botanical supplement for 28 days followed by a 30-day washout period. Probe drug cocktails of midazolam, caffeine, chlorzoxazone and debrisoquine were administered before (days -1, 0) and at the end of supplementation (days 27, 28). Pre- and post-supplementation phenotypic ratios were determined for CYP3A4, CYP1A2, CYP2E1 and CYP2D6 using 1-hydroxymidazolam/midazolam serum ratios (1-hour), paraxanthine/caffeine serum ratios (6-hour), 6-hydroxychlorzoxazone/chlorzoxazone serum ratios (2-hour) and debrisoquine urinary recovery ratios (8-hour), respectively.

Dose/Conc.(drug) : -
Result : Positive
Remark : The pupose of study was to assess the ability of single midazolam concentrations to predict midazolam AUC in the presence and absence of CYP3A modulation by GBE. Subjects received oral midazolam 8 mg before and after 28 days of GBE administration. The geometric mean raio (90% confidence intervals) of midazolam AUC 0-infinity - GBE / AUC 0-infinity pre - GBE was 0.66 (0.49-0.84) P = .03). Single midazolam concentrations between 2 and 5 hours correctly predicted the reduction in midazolam AUC following GBE exposure, but confidence intervals were generally wide.
