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

First Test GIR (Fasting), Then Reference GIR (Fasting)EXPERIMENTALParticipants received a single oral dose of 500 milligram (mg) of test Glucophage Immediate Release (GIR) tablet Sino-American Shanghai Squibb (SASS)/China) on Day 1 in treatment period 1 followed by a single oral dose of 500 mg reference GIR (Merck Santé in Semoy (MSS)/France) on Day 8 in treatment period 2 under fasting condition. There was a wash-out period of 7 days between each treatment period.

There was a wash-out period of 7 days between each treatment period.
First Test GIR (Fed), Then Reference GIR (Fed)EXPERIMENTALParticipants received a single oral dose of 500 mg of test GIR tablet (SASS/ China) on Day 1 in treatment period 1 followed by a single oral dose of 500 mg reference GIR (MSS/France) on Day 8 in treatment period 2 under fed condition. There was a wash-out period of 7 days between each treatment period.
