April 24, 2017 updated by: Yasser Yehia El-Sayed, Stanford University

Randomized Clinical Trial of Cervical Ripening and Labor Induction Using Stepwise Oral Misoprostol With or Without Intravaginal Isosorbide Mononitrate

The purpose of this study is to determine the efficacy and safety of the addition of intravaginal isosorbide mononitrate to an established protocol of oral misoprostol for cervical ripening and labor induction.
