8, GW4064 treatment caused a significant increase in the mRNA level of phase II conjugation enzymes and phase III transporters, including glutathione S-transferases (GSTs) (Gst[alpha]3 and Gst[alpha]4) as well as GSH metabolism-related genes (Gclm, GpxJ), glucuronosyltransferase (Ugtlal), sulfotransferases (SultJal) (phase II), and efflux transporters (Mrp2 and Bsep) (phase III).
Raltegravir is primarily metabolised by glucuronidation via uridine diphosphate glucuronosyltransferase (UGT) 1A1.
Coadministration of ISENTRESS with drugs that are strong inducers of uridine diphosphate glucuronosyltransferase (UGT) 1A1 may result in reduced plasma concentrations of raltegravir.
Findings on the roles of genetic polymorphisms in the UGT1A9 (UDP glucuronosyltransferase 1 family, polypeptide A9) gene for mycophenolate mofetil (16), the UGT2B7 (UDP glucuronosyltransferase 2 family, polypeptide B7) gene for acyl-glucuronide mycophenolic acid (17), and CYP3A5/ABCB1 for Tac exposure and acute rejection (18) in the FDCC study have previously been published.
One of these isoforms, encoded by the UGT1A1 (UDP glucuronosyltransferase 1 family, polypeptide A1) gene, is an enzyme that conjugates bilirubin with glucuronic acid in the liver, making bilirubin more water soluble (3).

The identified chromosomal region harbors the gene for the uridine diphosphate glucuronosyltransferase (UGT1A1, [6] UDP glucuronosyltransferase 1 family, polypeptide A1), the major enzyme of bilirubin glucuronidation, which mainly determines bilirubin elimination in humans.
The dose of ISENTRESS should be increased during coadministration with rifampin, a strong uridine diphosphate glucuronosyltransferase (UGT) 1A1, due to reduced plasma concentrations of ISENTRESS.
