Mechanistic basis of altered morphine disposition in nonalcoholic steatohepatitis.

J. Pharmacol. Exp. Ther. 352(3) , 462-70, (2015)

Morphine is metabolized in humans to morphine-3-glucuronide (M3G) and the pharmacologically active morphine-6-glucuronide (M6G). The hepatobiliary disposition of both metabolites relies upon multidrug...
