Sublingual Misoprostol 12.5 mcg Compared to Vaginal 25 mcg for Labor Induction

Labor induction is a common obstetric procedure, often necessitated by conditions like post-term pregnancy or preeclampsia. Current methods, including intravenous oxytocin and vaginal prostaglandins like misoprostol, have varying efficacy, safety profiles, and patient comfort levels. Vaginal misoprostol is widely used but can have variable absorption and local side effects. Exploring alternative routes like sublingual administration could offer advantages in terms of predictability, ease of use, and potentially a more favorable side effect profile, addressing a gap in optimizing induction protocols for term fetuses.

This randomized controlled trial (RCT) aimed to compare two misoprostol administration routes for labor induction in 300 women admitted for term induction with an alive fetus. Participants were randomized to receive either sublingual misoprostol 12.5 mcg or vaginal misoprostol 25 mcg. Subsequent doses, if needed, were planned at 50 mcg for both buccal (similar to sublingual in some contexts) or vaginal routes, as per the domain context. The primary endpoints were the comparative effectiveness and safety of the two routes for inducing labor.
