Usage of Glimepiride/Metformin Fixed-dose Combination with Insulin in Management of Type 2 Diabetes Mellitus: An Indian Experience

Abstract

Background: Type 2 diabetes mellitus (T2DM) poses a major public health burden. The present case-based questionnaire survey evaluated the treatment pattern and clinical experience of healthcare professionals (HCPs) in prescribing glimepiride/metformin fixed-dose combination (FDC) with insulin, with or without other oral hypoglycemic agents (OHAs), to patients with T2DM in the Indian setting. Material and methods: A retrospective, multicenter, observational, case-based questionnaire survey was conducted at several healthcare centers in India with the help of medical records of patients having T2DM, who were prescribed different strengths of glimepiride/metformin FDC. Data was collected from the patients’ medical records and were analyzed using statistical tests. Results: A total of 1,013 patients with T2DM were included in this study. The mean (± standard deviation [SD]) age of patients was 53.5 ± 13.9 years. Mean duration of diabetes was 6.3 ± 4.8 years. About 70.1% of the patients received glimepiride/metformin FDC as first-line therapy and 29.9% received it as second-line therapy. Around 66.3% of the patients in first-line glimepiride/metformin FDC group received insulin once a day, and the proportion increased to 86.8% of the patients in second-line therapy group. Other OHAs were used in 754 (74.4%) patients. About 18.2% (n = 185) patients reported change in weight, with a slightly larger number of patients having reduction in weight. There was considerable reduction in HbA1c, FPG and PPG in patients receiving glimepiride/metformin FDC with insulin, irrespective of OHA use. Efficacy and tolerability were reported as good to excellent for 96.2% and 94.8% patients, respectively. Conclusion: This case-based questionnaire survey shows the usage pattern of various strengths of glimepiride/metformin FDC with insulin
and the HCPs’ practice approach regarding early initiation of this combination in Indian patients with T2DM.
