Development of Physiologically Based Pharmacokinetic / Pharmacodynamic Model for Indomethacin Disposition in Pregnancy
Findings of a recent clinical study showed indomethacin has lower plasma levels and higher steady-state apparent clearance in pregnant subjects when compared to those in non-pregnant subjects reported in separate studies.
Liver-selective distribution in rats supports the importance of active uptake into the liver via organic anion transporting polypeptides (OATPs) in humans
Organic anion transporting polypeptide (OATP) 1B1 and 1B3 are key molecules that are involved in hepatic uptake related to drug elimination, and OATP-mediated drug interactions are of clinical concern.
