“…In addition, sorafenib can also inhibit the metabolism of canagliflozin by competing with canagliflozin for the same metabolic enzymes, leading to an increase in its blood concentration. According to a study by Karbowniket al [ 46 ], the exposure of tapentadol, which is mainly metabolized by UGT1A9 and UGT2B7, significantly increased when it was co-administered with sorafenib, indicating that UGT can mediate the interactions between the two drugs, which supports our conjecture. Second, sorafenib is not only a substrate for P-gp, BCRP, and MRP, but also an inhibitor of P-gp, while canagliflozin is a substrate for P-gp, BCRP, and MRP.…”

“…The method was successfully applied to investigate pharmacokinetic interactions between SOR and DAPA in rats. The dose of 100 mg/kg for SOR used in our study was selected from the previous studies [ 13 , 14 ], and DAPA was administered at 1 mg/kg, which was selected by converting recommended doses for patients in practice to animal doses [ 42 ]. In addition, UGT1A9 is functional in humans, whereas it is a pseudogene in rats, and Ugt1a7 compensated for the functions of UGT1A9 in rats [ 34 , 35 ].…”

“…The exposure of SOR may also be affected by enterohepatic recycling as SOR glucuronide is degraded by intestinal β-glucuronidase to become its parent formation again and transported into the blood [ 11 ]. In fact, numerous pharmacokinetic interaction studies of SOR involving the CYP3A4, UGT1A9, and transporters have been reported [ 12 , 13 , 14 ]. More importantly, according to in vitro studies, SOR is one of the most powerful inhibitors of human UGT enzymes identified to date [ 15 ].…”

“…About 50% of cancer patients undergoing active anti-cancer therapy and 90% of patients in the advanced stages experience severe pain [1]. In the clinical practice of cancer therapies, it can be expected that a combination of tyrosine kinase inhibitors (TKIs), such as sorafenib, and opioid analgesics, including morphine, are used, which, according to the WHO guidelines, is the first-choice opioid in the relief of cancer pain [2].…”
