In Vitro	Gemfibrozil 1-O-β-Glucuronide significantly inhibits the OATP2 (OATP1B1)-mediated uptake of Cerivastatin (CER; HY-129458) with an IC50 of 24.3 μM[1]. Gemfibrozil 1-O-β-Glucuronide inhibits CYP2C8-mediated M1, M23 formation with IC50s of 5.38 μM, 4.30 μM, and has no effects for CYP2C8-mediated M3 formation[1]. Gemfibrozil 1-O-β-Glucuronide has an IC50 of 243 μM for the CYP3A4- mediated metabolism[1].
