Description as written by the study sponsor.
Semaglutide belongs to a group of long-acting glucagon-like peptide 1 receptor agonists (GLP-1). Disorders in iron absorption have been linked to numerous medication, dietary, and nutrient interactions thus far. The study aimed to determine whether there is an effect of concomitant parenteral administration of semaglutide and oral iron preparations on iron absorption in patients with type 2 diabetes (T2DM).
Treatments tested
- semaglutide Drug
Patient demographic and clinical data was collected and entered into a database made specifically for the study. The patients were examined, and their vital signs and body measures were recorded. Before the introduction of semaglutide therapy all participants completed an oral absorption iron test (OIAT). As described in previous studies, OIAT was conducted in an outpatient setting. Following the initial OIAT therapy with semaglutide was started. Each subject received parenterally administered one-weekly semaglutide. To enhance glycaemic control, the therapy was up-titrated every four weeks. Initially, the dose was set at 0.25 mg once a week, four weeks later, it was raised to 0.5 mg once weekly, and four weeks after that, it was increased to 1 mg once weekly. After reaching the maximum maintenance dosage of 1 mg for two weeks, each T2DM patient completed a follow-up OIAT at week 10 of the study. Data from the first and subsequent OIATs were analysed statistically.
