Evaluating the clinical efficacy and safety of progestogens in the management of threatened and recurrent miscarriage in early pregnancy- A review of the literature
Journal Title: Indian Journal of Obstetrics and Gynecology Research - Year 2016, Vol 3, Issue 2
Abstract
Background Progestogens have been considered as a viable therapeutic option for the treatment of miscarriage for more than half a century. Aim: The aim of the present review is to provide a comprehensive view of the literature regarding the clinical efficacy and safety effects of progestogens for preventing recurrent miscarriages and managing threatened miscarriage during early pregnancy. Methods: A literature search was performed using electronic databases like Pubmed/ Medline to identify from 1953 to 2015. The search yielded around 27 original studies and review articles. Results: Dydrogesterone (oral) and various micronized progesterone (MCP) given orally, vaginally and intramuscularly are the most commonly used progestogens for the treatment of recurrent and threatened miscarriages. Pharmacokinetic profile of dydrogesterone exhibits better bioavailability, receptor affinity, quick onset of action and a better half-life imparting long and stable effect. Dydrogesterone exhibits 47% and 29% statistically significant reduction in odds ratio of threatened and recurrent miscarriage when compared to standard of care. While, literature supports use of MCP (vaginal), recent findings suggest no statistically significant difference in live birth rate when compared to placebo (65.8% vs. 63.3%). MCP (vaginal) is associated with vaginal discharge and irritation whereas dydrogesterone (oral) avoids vaginal discharge and no birth defects have been associated with its use. Conclusion: Treatment with dydrogesterone and other progestogens in general suggest dydrogesterone has number of advantages over other progestogens in terms of pharmacokinetic parameter clinical efficacy and safety profile. However, further studies are warranted to establish and promote the role of these progestogens in management of threatened and recurrent miscarriage.
