Comparison of Metformin Versus Glyburide for Blood Sugar Control in Women With Gestational Diabetes

Sponsor: Nishtar Medical University

Summary

The goal of this randomized clinical trial is to compare metformin and glyburide for controlling blood sugar in pregnant women with gestational diabetes mellitus (GDM) who require treatment with oral medication. The main question the study aims to answer is: Q: Is treatment failure less common with metformin or glyburide in pregnant women with GDM? The study will include 92 pregnant women aged 18-45 years with a singleton pregnancy, diagnosed with GDM between 13 and 33 weeks of pregnancy and requiring medication to control blood sugar. Participants will be randomly assigned to one of two treatment groups. Participants in the metformin group will receive metformin, starting at 850 mg once daily and increased to a maximum of 2,550 mg per day according to their blood sugar levels. Participants in the glyburide group will receive glyburide, starting at 2.5 mg twice daily and increased according to their blood sugar levels, up to a maximum of 20 mg per day. Blood glucose levels will be monitored regularly using a glucometer. Treatment will be considered successful when at least 80% of the recorded blood glucose measurements are within the target range. Treatment failure will be defined as fewer than 80% of blood glucose measurements being within the target range after up to 4 weeks of treatment. Participants who have treatment failure or cannot continue the assigned medication because of adverse effects will be switched to insulin therapy. Participants will be followed during pregnancy until delivery. The study will record treatment failure as the primary outcome and will also assess maternal outcomes, including preeclampsia, polyhydramnios, and preterm delivery, as well as newborn outcomes including macrosomia and the need for admission to a neonatal intensive care unit (NICU). The study will determine whether metformin or glyburide provides better blood sugar control and reduces the need to switch to insulin in pregnant women with gestational diabetes.
