Dapagliflozin reduced blood pressure. The mechanism for this effect is unclear but may involve osmotic diuresis or sodium loss. Although modest rises in hematocrit and blood urea nitrogen occurred,no meaningful changes were noted in electrolytes,serum creatinine,heartrate, or proportions of patients experiencing orthostatic hypotension to indicate dehydration. The estimated glomerular filtration rate and concentrations of cystatin-C did not show meaningful changes.Inaddition, AEs of renal impairment or failure— excluding those of decrease in creatinine clearance calculated using current body weight values at each study visit—were not over-represented with dapagliflozin. Taken together, these data suggest that dapagliflozin treatment was not associated with clinically relevant dehydration or impairment in kidney function.
