Study Endpoints

Primary Endpoints

Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Sampling Time (AUC 0-t) of Metformin
Pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14 post-dose on Day 1 and Day 8; 24, 30, 36 hours post-dose on Day 2 and 9; 48 hours post-dose on Day 3 and 10

Area under the plasma concentration versus time curve from time zero to the last sampling time t at which the concentration was at or above the lower limit of quantification (LLQ). AUC0-t was to be calculated according to the mixed log-linear trapezoidal rule.

Maximum Observed Plasma Concentration (Cmax) of Metformin
Pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14 post-dose on Day 1 and Day 8; 24, 30, 36 hours post-dose on Day 2 and 9; 48 hours post-dose on Day 3 and 10

Pharmacokinetic (PK) parameter Cmax was obtained directly from the concentration versus time curve.

Secondary Endpoints

Time to Reach Maximum Plasma Concentration of Metformin
Pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14 post-dose on Day 1 and Day 8; 24, 30, 36 hours post-dose on Day 2 and 9; 48 hours post-dose on Day 3 and 10
Apparent Terminal Half-Life (t1/2) of Metformin
Pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14 post-dose on Day 1 and Day 8; 24, 30, 36 hours post-dose on Day 2 and 9; 48 hours post-dose on Day 3 and 10
Area Under the Plasma Concentration-Time Curve From Time 0 to Infinity (AUC0-inf) of Metformin
Pre-dose, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14 post-dose on Day 1 and Day 8; 24, 30, 36 hours post-dose on Day 2 and 9; 48 hours post-dose on Day 3 and 10
