Comparative Efficacy of Tirzepatide, Teneligliptin, and Empagliflozin in HbA1c Reduction in Patients with Type 2 Diabetes: A Systematic Review and Meta-Analysis

This study’s objective was to evaluate the effectiveness of three different families of drugs (Empagliflozin [an SGLT-2 inhibitor], Tirzepatide [a GLP-1 receptor co-agonist], and Teneligliptin [DPP-4 inhibitor] used in the treatment of type 2 diabetes in lowering HbA1c levels in people with type 2 diabetes mellitus (T2DM). The effectiveness of different families of diabetic drugs was assessed using a meta-analytic approach. Data were gathered from a variety of research publications using ICTRP, CT.gov, and PubMed databases. The data were analyzed, and conclusions were drawn using forest plots. Teneligliptin (a DPP-4 Inhibitor) substantially lowered HbA1c levels in T2DM patients compared to other classes of T2DM drugs with a P-value of 0.0002 and 95% CI -0.63 [-0.97 to -0.30] after reviewing many pertinent articles. The pooled data analysis showed that Tirzepatide and Empagliflozin did not significantly lower HbA1c levels, with the P-value for Tirzepatide being P = 0.55 and for Empagliflozin, it was P = 0.64. According to our research, Teneligliptin may be more effective than Empagliflozin and Tirzepatide as a monotherapy for lowering HbA1c levels in T2DM patients. To corroborate these findings, further research studies are required.
