CYP inducers and inhibitors appear to be relevant to R dosing. Xenobiotics in general have the ability to induce the mRNA expression of CYP isoforms and according to the FDA draft guideline for drug–drug interaction studies, the cytochrome induction properties of any xenobiotics or compounds can be determined by examining their mRNA levels in suitable test models (FDA 2006, 2012).
