GXR RM (Glucophage® Extended Release Reduced Mass) 500 Milligram (mg) Korea Bioequivalence (BE) Study

A Randomized Phase I, Open-Label, Active-Controlled Study Assessing The BE Between Single Doses of 500 mg GXR RM Tablets and 500 mg GXR Tablets Under Fasted and Fed State in Two 2-Way Crossover Groups of Healthy Participants

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.

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
