Empagliflozin-based quadruple oral therapy for type 2 diabetes: a prospective cohort study

The management of Type-2 Diabetes Mellitus (T2DM) remains challenging in cases of poor glycemic control despite triple Oral Hypoglycemic Agent (OHA) therapy. This prospective cohort study aimed to assess the effectiveness of Empagliflozin as part of a quadruple OHA regimen over a 7-year follow-up period in 575 adult patients with uncontrolled T2DM on a triple OHA regimen and who were unwilling to initiate insulin therapy. Overall, 92.5% of patients achieved their target HbA1c levels. Significant reductions were observed in all glycemic parameters after 68 months (p < 0.001). Weight and BMI significantly decreased, whereas waist circumference remained unchanged. Lipid profiles showed significant improvements in total cholesterol, LDL, and triglycerides, while HDL levels did not change significantly. Blood pressure trends revealed significant reductions in both diastolic blood pressure (DBP) and mean arterial pressure (MAP), though systolic blood pressure (SBP) remained relatively stable. Our study indicates that adding empagliflozin to a drug regimen consisting of multiple OHAs can effectively control glycemia in T2DM patients with more pronounced target achievement (< 7%) and HbA1c reduction along with improvement in cardiometabolic parameters, suggesting its potential as a promising alternative for long-term glycemic management.
