Summary
The purpose of this study was to assess bioequivalence (BE) of newly developed Glucophage® XR (GXR) reduced mass (RM) tablet (metformin hydrochloride 500 milligrams (mg) test tablet) and marketed Glucophage ® XR tablet (metformin hydrochloride 500 mg reference tablet) following single oral dose administration under fasted and fed conditions by comparing pharmacokinetics, safety and tolerability between test and reference in healthy participants.
Eligibility Criteria
Inclusion Criteria
- All values for hematology and biochemistry tests of blood and urinalysis (especially Estimated Glomerular Filtration Rate [eGFR] greater than [>] 80 milliliters per minute per 1.73 square meter [80 ml/min/1.73 m^2] and normal Creatinine) within the normal range or showing no clinically relevant deviation as judged by the Investigator
- Are not having congenital or chronic diseases, nor pathological symptoms based on the screening
- Have no history of gastrointestinal resection that may affect drug absorption
- Have no history of psychiatric disorder within 5 years prior to screening
- Vital signs (body temperature [tympanic], blood pressure [BP], and pulse rate in sitting position) within the normal range or showing no clinically relevant deviation as judged by the Investigator
- Electrocardiogram recording (12-lead) without signs of clinically relevant pathology in particular QTc (Bazett) less than or equal to [<=] 450 millisecond (ms)
- Non-smoker (that is [i.e.] zero cigarettes, pipes, cigars or others) at least three months before study entry
- Negative screen for Hepatitis B surface antigen (HBsAg) and Hepatitis B Virus antibody (anti-HBc), Hepatitis C Virus antibody (anti-HCV) and Human Immunodeficiency Virus antibodies (anti-HIV 1 and 2) and Rapid Plasma Reagin Antibody (RPR Ab)
- Have a body weight within the range 55 to 95 kilograms (kg) and a Body Mass Index (BMI) within the range 18.5 to 29.9 kilograms per square meter (kg/m^2) (inclusive)

- Participants who took drugs that significantly induce (e.g., barbiturate) or inhibit drug metabolism enzymes, and those drugs that may alter metformin pharmacokinetic (pK), most importantly organic cation transporter 1/2 [OCT1/2] inhibitors and inducers, within 30 days prior to screening
- Use of a concomitant drug. However, any medications that are considered necessary for participant's welfare and will not interfere with the trial medication may be given at the discretion of the investigator
- Use of any medication that may affect the outcome of the study within 10 days prior to screening and during study conduct
- Participation in another bioequivalence or other clinical studies where the last administration of previous study medication was within
