What this trial studies
This randomized phase 4 trial compares two oral medicines, metformin and glyburide, for managing blood glucose in pregnant women with gestational diabetes who require drug therapy. Participants are 18 to 45 years old with singleton pregnancies and GDM diagnosed between 13 and 33 weeks; they are assigned to either metformin with dose adjustments up to 2,550 mg daily or glyburide with dose adjustments up to 20 mg daily. The primary question is which treatment has a lower rate of treatment failure, defined by the study protocol. Blood glucose levels will be monitored to guide dose adjustments and evaluate outcomes. The trial is sponsored by Nishtar Medical University, with sites at Nishtar Medical University and Hospital in Multan, Pakistan.
Why it matters
Potential benefit: If successful, the better-performing medication could simplify blood sugar control for pregnant patients with GDM.
How similar studies have gone: Earlier studies have compared these drugs for GDM with mixed results; this trial adds randomized data in a Phase 4 setting.
