Once-weekly semaglutide (0.5 mg and 1.0 mg) as an add-on to metformin significantly improves glycemic control (HbA1c), reduces body weight, and lowers blood pressure compared to once-daily sitagliptin in patients with type 2 diabetes.

For patients with Type 2 Diabetes on metformin who need better blood sugar and weight control, switching to once-weekly semaglutide is more effective than switching to the oral drug sitagliptin. Semaglutide lowers HbA1c, weight, and blood pressure more significantly. However, be aware that semaglutide carries a higher risk of side effects and treatment discontinuation compared to sitagliptin.

the findings revealed that once-weekly semaglutide showed substantially improved hba1c (WMD: −0.98; 95% ci: −1.28, −0.69, p-value: < 0.0001; i2: 100%), systolic (WMD: −3.73; 95% ci: −5.42, −2.04, p-value: <0.0001; i2: 100%) and diastolic blood pressures (WMD: −0.66; 95% ci: −1.02, −0.29, p-value: 0.0005; i2: 100%), and body weight (WMD: −3.17; 95% ci: −3.84, −2.49, p-value: <0.00001; i2: 100%) compared to once-daily sitagliptin.
