Arm && Interventions

Group	Intervention	Description
First Glucophage XR (Test), Then Glucophage XR (Comparator)	Glucophage XR (Comparator drug)	Participants received single oral dose of 750 milligram (mg) Glucophage® XR tablet manufactured by PT Merck Tbk, Jakarta, Indonesia (Test Drug) in treatment period 1 followed by single oral dose of 750 mg Glucophage® XR tablet manufactured by Merck Santé, Semoy, France (Comparator Drug) in treatment period 2 under fasting conditions. The two periods were separated by a 7-day wash-out period.

Primary Outcome Measures

Name	Time	Method
Maximum Observed Plasma Concentration (Cmax) of Metformin	Pre-dose, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 10, 12, 16, 24, and 32 hours post-dose on Day 1	The maximum plasma concentration of Metformin.
Area Under the Plasma Concentration-Time Curve From Time Zero to Last Measurable Concentration (AUC0-t) of Metformin	Pre-dose, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 10, 12, 16, 24, and 32 hours post-dose on Day 1	Area under the plasma concentration-time curve from zero to the time of the last quantifiable concentration.

Secondary Outcome Measures

Name	Time	Method
Area Under Plasma Concentration Time Curve From Time Zero Extrapolated to Infinity (AUC0-inf) of Metformin	Pre-dose, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 10, 12, 16, 24, and 32 hours post-dose on Day 1	AUC (0-inf) is defined as the area under the plasma concentration versus time curve (AUC) from time zero (predose) to extrapolated infinite time (0-inf).
Time to Reach Maximum Observed Plasma Concentration (Tmax) of Metformin	Pre-dose, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 10, 12, 16, 24, and 32 hours post-dose on Day 1	Time of the maximum drug concentration.
Terminal Elimination Half-life in Plasma (t½) of Metformin	Pre-dose, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 10, 12, 16, 24, and 32 hours post-dose on Day 1	Elimination Half Life (t1/2) was defined as the time required for the concentration or amount of drug in the body to be reduced by one-half.
Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious TEAEs	Up to Day 51	An adverse event (AE) was defined as any untoward medical occurrence in a participant which does not necessarily have a causal relationship with the treatment. An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, whether or not considered related to the medicinal product. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. The term TEAE is defined as AEs starting or worsening after the first intake of the study drug. Number of participants with TEAEs included participants with both non serious and serious TEAEs.
