“…Erythromycin is reported to be mostly metabolized by CYP3A (Karlsson et al, 2013), consistent with the high CYP3A f m value observed in this study (Table 2). Tizanidine is a CYP1A2 substrate with reported inhibition of 85% by furafylline (Granfors et al, 2004), which is in line with our measured value of 83%.…”

“…Although it is reasonable to assume that the free liver concentration could be similar to the free plasma concentration when a perfusion-limited model is used, the use of this assumption to determine the metabolite concentration at interacting sites is still uncertain, especially for a highly lipophilic metabolite such as MDEA. Other parameters, such as free inhibitory metabolite concentration in the gut (Yang et al, 2007;Karlsson et al, 2013) and in vivo inhibition potency of the inhibitory metabolite, can also affect the prediction. A good understanding of the source of uncertainty for these parameters and its impact on the prediction is important.…”

“…Though not often accounted for, the fraction that escapes luminal degradation, by, e.g., digestive enzymes or conversion by the intestinal microbiota, also affects the oral bioavailability. This fraction is generally assumed to be part of f gut , as an additional source of gut metabolism (Karlsson et al, 2013).…”
