A retrospective comparative study to evaluate the efficacy and safety of mifepristone with misoprostol over misoprostol alone in induction in labor

Background The aim is to compare the improvement in pre-induction Bishop’s score, proportion of patients going in labor and induction–delivery interval after using the Misoprostol versus Mifepristone and Misoprostol as cervical ripening and labor inducing agent.

Methods It is retrospective comparative study conducted on 110 women. Women were randomized in group A and in group B of 55 patients in each group. Group A received tab Mifepristone 200 mg orally on day 1 followed by Misoprostol 25 ug after 48 hours and continued 6 hourly till maximum four tablets and group B patients received tablet Misoprostol 25ug and continued 25ug 6hrly maximum 4 doses. Women observed for improvement in Bishop‟s score, induction-delivery interval and requirement of subsequent doses of Misoprostol.

Results Present study concluded that tablet Mifepristone is an efficient cervical ripening and inducing agent of labor as pre-induction Bishop’s score was improved. 36.4%patients went into labor only with tablet Mifepristone. The mean induction-delivery interval was,19±12.2hrs in Group 1 as compare to 13.1±13.0 hrs in Group 2. Mean Bishop’s score observed in Group 1 were 2.5±1.78 and 1.67±1.25 in Group 2. It was observed that there was significant improvement in the Bishop’s score after giving Mifepristone to the patients; mean Bishop’s 24hrs after mifepristone were 4.03±1.80. Repeated dose of Misoprostol required in Group 1 was observed to be higher than group 2 as shown in table 8. Mean misoprostol doses required in group 1 was 2.56±1.15 as compared to 1.71±1.58 in group 2.

Conclusions Mifepristone with Misoprostol reduce the induction delivery interval and more potent in combination for induction of labour as compared to Misoprostol alone.
