Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients diagnosed with arrested pre-term labor following tocolytics at 24-34 gestational weeks will be randomly allocated to receive either vaginal micronized progesterone 400 mg/day or no treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Since progesterone derivatives are useful in preventing preterm labor in cases of risk factors or previous preterm labor, we hypothesize that they will also show efficacy in pregnancy prolongation in women whose preterm labor was arrested following tocolytic treatment.

Patients diagnosed with arrested pre-term labor following tocolytics at 24-34 gestational weeks will be randomly allocated to receive either vaginal micronized progesterone 400 mg/day or no treatment.

This study has the potential to find a treatment to prevent preterm labor and thus to reduce neonatal morbidity and mortality.
