Drug Interactions of SGLT2 Inhibitors (Gliflozins)




   §    Sodium glucose cotransporter 2 (SGLT2) inhibitors are antidiabetic drugs.
   §    SGLT2 inhibitors include Canagliflozin, Dapagliflozin, Empagliflozin, Ertugliflozin and other Gliflozins.
   §    SGLT2 inhibitors prevent the reabsorption of glucose and facilitate its excretion through urine by inhibiting Sodium-glucose co-transporter-2 in the proximal convoluted tubule, which results in decrease in blood sugar.
   §    SGLT2 inhibitors such as Dapagliflozin, Canagliflozin and Ipragliflozin are metabolised by glucuronidation predominantly by UGT1A9 enzyme.
   §    The drugs inhibiting UGT1A9 such as Mefenamic acid and Probenecid slightly increased the plasma exposure of Dapagliflozin and Canagliflozin respectively.
   §    Rifampicin and other UGT inducers such as Phenytoin, Phenobarbital and Ritonavir were observed to decrease the plasma levels of Canagliflozin, insignificantly.
   §    The pharmacokinetics parameters of Warfarin, Digoxin, Simvastatin, Valsartan, Oral contraceptives containing Ethinyl estradiol and Levonorgestrel and Thiazide diuretics (Hydrochlorothiazide) were not altered significantly by the concomitant administration of Canagliflozin or Dapagliflozin.
   §    Coadministration of SGLT2 inhibitors such as Canagliflozin, Dapagliflozin and Ipragliflozin with other oral antidiabetic drugs did not result in any clinically significant interactions.
   §    SGLT2 inhibitors could be coadministered with any medicines without dosage adjustments except Canagliflozin which needs higher dosage while using along with UGT enzyme inducers. 
   §    Healthcare professionals through the screening, education, and follow up on suspected drug interactions could reduce the risk of adverse effects.
   §    The patients are encouraged to ask their doctor or pharmacist to look over their list for any potentially dangerous combinations.
   §    It is recommended that people fill all their prescriptions at one pharmacy, if possible.
