Effect of Gliclazide or Gliclazide plus Metformin Combination on Glycemic Control in Patients with T2DM in India: A Real-World, Retrospective, Longitudinal, Observational Study from Electronic Medical Records

Abstract

Abstract Background The efficacy of gliclazide has been reported in clinical trials in India. However, real-world data on the effectiveness of gliclazide in India is unavailable. Objective To provide real-world evidence regarding the effectiveness of gliclazide or gliclazide + metformin fixed-dose combination or separate medications, used either as monotherapy or as the latest add-on to other antihyperglycemic agents in reducing glycated hemoglobin (HbA1c) levels in Indian patients with type 2 diabetes mellitus (T2DM). Methods Electronic medical record data of adult patients who were diagnosed with T2DM who were newly initiated on or had been prescribed gliclazide or gliclazide + metformin combination for 7% was − 0.8% (− 1.26, − 0.34) in gliclazide only group; − 1.6% (− 1.89, − 1.31; p < 0.001) in gliclazide + metformin group; − 1.2% (− 1.50, − 0.90; p < 0.001) in add-on gliclazide group; and − 1.4% (− 1.75, − 1.05; p < 0.001) in add-on gliclazide + metformin group. Gliclazide once daily was the most prescribed regimen in the gliclazide only group (72.7%), with 60 mg being the most prescribed modified-release dose (62.5%). Gliclazide + metformin twice daily was the most prescribed regimen in the gliclazide + metformin group (69.3%) with 80 mg + 500 mg being the most prescribed immediate-release dose (62.9%). Gliclazide and gliclazide + metformin were most added as an adjunct to existing prescriptions of biguanides (83.4%) or insulin (64.3%), respectively. Conclusion Gliclazide or gliclazide + metformin prescribed as mono- or add-on therapy during routine clinical practice effectively reduced HbA1c in Indian patients with T2DM, thus validating the use of gliclazide and gliclazide + metformin for managing T2DM in India.
