Abstract

Introduction: Women with gestational diabetes due to concerns about teratogenicity and neonatal hypoglycemia are rarely treated with sulfonylureas. There is little information about the effects of these drugs in this group of women. This study was performed with the aim to compare the therapeutic effects of glibenclamide and insulin in treatment of gestational diabetes.
Methods: This clinical randomized interventional study was performed on 90 women with gestational diabetes requiring treatment in 2010-2011. Women were randomly assigned to treatment with glibenclamide or insulin. Subcutaneous insulin 20 units twice a day was prescribed and, if needed, increased weekly. In the other group, 2.5 mg glibenclamide orally, once a day was started and if needed increased weekly up to a maximum dose of 20 mg. Treatment goal was fasting blood sugar 60-90 and after the food less than 120 mg/dl. Data were analyzed by SPSS software version 16 and Chi-square, independent t, Fisher exact and Mann-Whitney tests. PResults: Only one of the women in the glibenclamide group required to insulin for controlling blood sugar. There was no significantly difference between two groups in the percentage of infants with macrosomia (0.649), Oligohydramnios (0.304), policitemia (0.304), hypoglycemia (0.325), Polyhydramnios (0.778) and other neonatal complications.
Conclusion: Glibenclamide has equivalent effectiveness with insulin in the treatment of gestational diabetes.
