RESUMEN
Objective: Semaglutide is the first glucagon-like peptide- 1 receptor agonist with oral and subcutaneous formulations. We studied patient adherence and clinical response following their prescription in a primary care setting. Method(s): We searched for patients starting semaglutide between October 2020 to November 2021 in primary care registries in Dudley, West Midlands. We tracked their collection of medications for up to six months, changes in HbA1C and weight if these data were available at 26 weeks (range 22-52 weeks), with significance tested using a t-test. Patients prescribed both formulations were excluded. Result(s): Clinical data were available in 180 of the 443 patients. Baseline HbA1c was 79.0 +/- 18.6mmol/mol (Ozempic) and 81.9 +/- 19.3mmol/mol (Rybelsus) and pre-treatment weight was 108.4 +/- 10.5 kg (Ozempic) and 104.3 +/- 26.7 kg (Rybelsus). 62.8% of patients were of non-white ethnicity and 82.8% were on >= two anti-diabetic drugs. In patients with six-month follow-up data, mean reduction in HbA1c and weight was 17.1 +/- 20.8mmol/ mol and 3.9 +/- 6.2 kg (Ozempic n = 53, p < 0.01) and 18.2 +/- 14.5mmol/mol and 5.9 +/- 4.2 kg (Rybelsus n = 5, p < 0.05). Drug continuation rates were measured in 324 patients. 3.2% and 19.0% of patients for Ozempic and Rybelsus respectively did not obtain further prescriptions after their initial script. At six months, 87.2% continued with Ozempic and 57.2% with Rybelsus. Conclusion(s): This study demonstrates similarly significant reductions in HbA1c and weight with Ozempic and Rybelsus, despite the complexity of follow-up during Covid-19 restrictions. The lower adherence to Rybelsus warrants further study.
