Abstract

Introduction: Gestational diabetes mellitus (GDM), the most frequent medical complication of pregnancy, is associated with several adverse outcomes over the short- and long-term for both mother and offspring. Standard treatment for GDM consists of insulin injections. Oral hypoglycemic agents (OHAs), on the other hand, are still the subject of controversy. Although OHAs are seemingly as efficient as insulin and may provide better quality of life, congenital malformations and unknown long-term effects are still feared.

Areas covered: Recent data on the pharmacokinetics of two OHAs (glyburide and metformin) and their clinical use for GDM are reviewed, with a focus on clinical trials and observational studies comparing insulin with glyburide or metformin (1960 – 2010). The review will provide a comprehensive overview of the pros and cons of OHA usage, an appreciation of OHAs' efficiency for the purpose of controlling glycemia and embryogenetic basics relating to congenital malformations.

Expert opinion: While insulin treatment is an effective therapy for controlling maternal glycemia, it nevertheless requires sufficient education and skills on the part of the patient to manage properly and may cause hypoglycemia, fear and anxiety. Oral treatment as a more user-friendly alternative may thus facilitate the control of GDM in some patients.
