Cervical Ripening With Misoprostol vs Isosorbide Mononitrate ; A Parallel -Arm Randomized Controlled Trial

The Misoprostol group (n=40) were Misoprostol cases, a synthetic PGE1 in the form of vaginal tablets of 25 µg (Vagiprost; ADWIA Co/Egypt) applied locally to the posterior fornix every 4 hours for cervical ripening before induction of labor is started (up to 3-doses).

"The Isosorbide Mononitrate group (n=40) were nitric acid donor cases applied to the posterior fornix prior to induction of labor. Isosorbide mononitrate (IMN) (Monomack; Mack Pharmaceutics; Jordan) in a vaginal dose of 40 mg was used every 4 hours (up to 3 doses).~Women who scored a BS of \> 6 from the assigned time were labelled as (1), after the passage of 40 hours, while those women whose BS was less than 6 were labelled (0) for construction of the Kaplan Meier curve for both groups."
