Study Endpoints

Primary Endpoints

Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Sampling Time (AUC 0-t) of Metformin (GIR Tablet Active Ingredient)
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3

Area under the plasma concentration vs 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 (GIR Tablet Active Ingredient)
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3

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

Secondary Endpoints

Time to Reach Maximum Plasma Concentration of Metformin (GIR Tablet Active Ingredient)
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Apparent Terminal Half-Life (t1/2) of Metformin (GIR Tablet Active Ingredient)
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Area Under the Plasma Concentration-Time Curve From Time 0 to Infinity (AUCinf) of Metformin (GIR Tablet Active Ingredient)
Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
