Pharmacotherapy options for labor induction.

ABSTRACT

INTRODUCTION: Induction of labor remains one of the most commonly performed procedures in the US and in other developed countries around the world. Various agents for cervical ripening are used prior to induction; the most commonly used are prostaglandins and oxytocin. The ideal agent is one that decreases time to vaginal delivery without compromising maternal and/or fetal safety. AREAS COVERED This article reviews the current pharmacologic methods available for induction of labor. Although these agents have been extensively studied and their safety and efficacy profile are well accepted, there is still ongoing research to determine the safest and most effective method. The article discusses the impact of pharmacogenomics as it relates to the most common induction agents. The dosing, route of administration, and side effects of these agents are reviewed. EXPERT OPINION Prostaglandins and oxytocin have been proven to be safe and effective methods of induction. However, the optimal medication for induction is yet to be determined. Although there are currently no pharmacogenomic findings that affect dosing of either prostaglandins or oxytocin, this is a growing area of research. In the near future, it may become clear that there is no 'one regimen for all' when selecting an induction or cervical ripening agent, or any other pharmaceutical altogether.
