    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.

    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

  • Maximum Observed Plasma Concentration (Cmax) of Metformin

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

    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

    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 Tlast Extrapolated to Infinity (AUCextra) 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

  • Elimination Rate Constant (Lambda z) 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
