| Outcome Measures: |
Primary: Cmax (Maximum Observed Plasma Concentration), Whole venous blood samples of 5 mL were be collected from a peripheral vein in each period at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose for Group 1 and 2. Pharmacokinetic (PK) blood samples were collected at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, 48, 60 and 72 h post-dose for Group 3. Plasma was obtained from centrifugation, frozen and analyzed. Cmax was obtained directly from experimental observations., Up to 72 hours|Tmax (Time of Maximum Observed Plasma Concentration), Whole venous blood samples of 5 mL were collected from a peripheral vein in each period at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose for Group 1 and 2. PK blood samples were collected at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, 48, 60 and 72 h post-dose for Group 3. Plasma was obtained from centrifugation, frozen and analyzed. Tmax was obtained directly from experimental observations., Up to 72 hours|T1/2 (Apparent Terminal Elimination Half-life), Whole venous blood samples of 5 mL were collected from a peripheral vein in each period at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose for Group 1 and 2. PK blood samples were collected at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, 48, 60 and 72 h post-dose for Group 3. Plasma was obtained from centrifugation, frozen and analyzed. T1/2 was obtained directly from experimental observations., Up to 72 hours|AUC0-inf (Area Under the Plasma Concentration-time Curve From Time 0 to Infinity), Whole venous blood samples of 5 mL were collected from a peripheral vein in each period at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose for Group 1 and 2. PK blood samples were collected at pre-dose and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, 48, 60 and 72 h post-dose for Group 3. Plasma was obtained from centrifugation, frozen and analyzed. AUC0-inf was estimated for each subject., Up to 72 hours | Secondary: Urinary Glucose Excretion up to 0-72 hr, Pre-dose urine samples were collected from -12 to 0 h for baseline measurement. Subjects was instructed to empty their bladder prior to dosing. Post-dose urine was collected in 4 batches for Groups 1 and 2 at 0 to 12 h, 12 to 24 h, 24 o 36 h, and 36 to 48 h collections. Post-dose urine was collected in batches for Group 3 at 0 to 12 h, 12 to 24 h, 24 to 36 h, 36 to 48 h, 48 to 60 h and 60 to 72 h., up to 0-72 hr
