Oral semaglutide improves glycemic control in type 2 diabetes

Última actualización 5 de julio de 2026

Key finding

The estimated treatment difference (ETD [95% CI]) was -2 (-4, -1) mmol/mol.

This study compared the efficacy and safety of oral semaglutide to sitagliptin in adults with inadequately controlled type 2 diabetes. Results indicated that oral semaglutide led to significantly greater reductions in HbA1c and body weight.

Plain-language summary

What this paper says

A plain-language read of the study’s main message and where it applies.

Study focus

This study compared the efficacy and safety of oral semaglutide to sitagliptin in adults with inadequately controlled type 2 diabetes. Results indicated that oral semaglutide led to significantly greater reductions in HbA1c and body weight.

Clinical relevance

These findings are significant for clinicians treating patients with type 2 diabetes, as they highlight the potential of oral semaglutide as a more effective alternative to sitagliptin. Improved glycemic control and weight loss can lead to better overall health outcomes for patients, reducing the risk of diabetes-related complications.

Keep in mind

The study's population may not be representative of all adults with type 2 diabetes. Limited long-term safety data beyond 26 weeks. Potential for bias due to the open-label design.
