The metabolism of dapagliflozin is primarily mediated by UGT1A9-dependent glucuronide
conjugation. The major metabolite, dapagliflozin 3-O-glucuronide, is not an SGLT2 inhibitor.
In invitro studies, dapagliflozin and dapagliflozin 3-O-glucuronide neither inhibited CYP 1A2, 2C9,
2C19, 2D6, 3A4, nor induced CYP1A2, 2B6 or 3A4. Therefore, dapagliflozin is not expected to alter
the metabolic clearance of co-administered medicines that are metabolised by these enzymes.
Dapagliflozin is a weak substrate of the P-glycoprotein (P-gp) active transporter and dapagliflozin 3-
O-glucuronide is a substrate for the OAT3 active transporter. Dapagliflozin or dapagliflozin 3-O-
glucuronide did not meaningfully inhibit P-gp, OCT2, OAT1, or OAT3 active transporters.
The dependence of dapagliflozin elimination on dapagliflozin 3-O-glucuronide formation in humans
also suggests the possibility of interactions mediated by UGT1A9. Ketoconazole is an in vitro
inhibitor of dapagliflozin 3-O-glucuronide formation by UGT1A9 (IC50 = 32 μM).
Effects of other medicines on DEPAGLOZ
The pharmacokinetics of DEPAGLOZ are not altered by metformin (a human OCT-1 and hOCT-2
substrate), pioglitazone (a CYP2C8 [major] and CYP3A4 [minor] substrate), sitagliptin (a human
OAT-3 substrate and P-glycoprotein substrate), glimepiride (a CYP2C9 substrate), voglibose (an
alpha-glucosidase inhibitor), hydrochlorothiazide, bumetanide, valsartan, or simvastatin (a CYP3A4
substrate). A 22 % decrease in dapagliflozin systemic exposure following co-administration with
rifampicin was considered not to be large enough to warrant a dose adjustment.
Following coadministration of dapagliflozin with mefenamic acid (an inhibitor of UGT1A9), an
increase in dapagliflozin systemic exposure was seen, but with no clinically meaningful effect on
24-hour urinary glucose excretion. No dose adjustment is recommended.
Effect of DEPAGLOZ on other medicines
DEPAGLOZ did not alter the pharmacokinetics of metformin (an hOCT 1 and hOCT 2 substrate),
pioglitazone (a CYP2C8 [major] and CYP3A4 [minor] substrate)35, sitagliptin (a hOAT 3 substrate
and P-glycoprotein substrate), glimepiride (a CYP2C9 substrate), hydrochlorothiazide, bumetanide,
