Outcomes
Primary Outcomes
Geometric Mean of Maximum Observed Plasma Concentration (Cmax) of Dapagliflozin
Time Frame: 11 time points: Immediately pre-dose, 0.5, 0.75, 1.0, 1.5, 4, 8, 12, 14, 24, and 48 hours post-dose
Maximum observed plasma concentration (Cmax) was measured by plasma concentration of Dapagliflozin over time. The geometric means are reported in nanograms per milliliter (ng/mL).
Median Time of Maximum Observed Plasma Concentration (Tmax) of Dapagliflozin
Time Frame: 11 time points: Immediately pre-dose, 0.5, 0.75, 1.0, 1.5, 4, 8, 12, 14, 24, and 48 hours post-dose
Time of maximum observed plasma concentration (Tmax) for Dapagliflozin was derived from plasma concentrations versus time data. Medians were reported in hours (h).
Geometric Mean of Area Under the Concentration-time Curve From Time Zero to the Time of the Last Quantifiable Concentration [AUC(0-T)] of Dapagliflozin
Time Frame: 11 time points: Immediately pre-dose, 0.5, 0.75, 1.0, 1.5, 4, 8, 12, 14, 24, and 48 hours post-dose
Area under the concentration-time curve from time zero to time of the last quantifiable concentration (AUC(0-T)) was measured by plasma concentration of Dapagliflozin over time. The geometric means are reported in nanogram hours per milliliter (ng\*h/mL).
Mean Plasma Half-life (T-HALF) of Dapagliflozin
Time Frame: 11 time points: Immediately pre-dose, 0.5, 0.75, 1.0, 1.5, 4, 8, 12, 14, 24, and 48 hours post-dose
Plasma half-life (T-Half) for Dapagliflozin was derived from plasma concentrations versus time data. Means are reported in hours.
Geometric Mean of Apparent Clearance After Extravascular Administration (CL/F) of Dapagliflozin
Time Frame: 11 time points: Immediately pre-dose, 0.5, 0.75, 1.0, 1.5, 4, 8, 12, 14, 24, and 48 hours post-dose
Apparent clearance after extravascular administration (CL/F) of Dapagliflozin was derived from plasma concentrations versus time data. Geometric means are reported in milliliters per minute (mL/min).
Geometric Mean of Area Under the Plasma Concentration-time Curve From Time Zero Extrapolated to Infinite Time [AUC(INF)] of Dapagliflozin
Time Frame: 11 time points: Immediately pre-dose, 0.5, 0.75, 1.0, 1.5, 4, 8, 12, 14, 24, and 48 hours post-dose
Area under the plasma concentration-time curve from time zero extrapolated to infinite time was derived from concentration versus time data. Geometric means are reported in nanogram hours per milliliter (ng\*hr/mL).
