  • Calculation of derivation of pharmacodynamic variables (inhibition of plasma glucose re-absorption, 24 hour urine glucose excretion, inhibition of rate of gut glucose absorption by measuring plasma glucose, insulin and GIP). [ Time Frame: plasma glucose will be drawn on Day 5, creatinine will be drawn at pre-dose of Day 4 and of Day 5, glucose and insulin will be drawn on Day 5 , Day 5 for GIP, urine will be collected on Day 5 in 4-hour intervals ]
  • To examine the safety and tolerability of the combination of dapagliflozin and metformin [ Time Frame: Adverse events and laboratory variables assessed throughout both 5-day treatment periods, and a follow-up visit 5-10 days later ]

A Study to to Assess the Effect of Dapagliflozin When Administered Once a Day Versus Twice a Day on Blood Glucose
An Open-label, Randomised, Two-period Crossover Study to Assess the Effect of Dapagliflozin on Percent Inhibition of Glucose Re-absorption When Administered Once a Day (10 mg OD) Versus Twice a Day (5 mg BID) in Healthy Male and Female Volunteers
The primary objective of the study is to assess the effect of dapagliflozin on the amount of glucose in the blood and urine when dapagliflozin is administered once a day (10 mg) versus twice a day (5 mg every 12 hours) after five days of dosing.
