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.
