Used in medicine to induce labor in pregnant women by promoting cervical ripening and uterine contractions. It is administered as a vaginal suppository or gel in obstetrics when natural labor is delayed or needs to be initiated for maternal or fetal health reasons. Also used in newborns to maintain the patency of the ductus arteriosus until corrective surgery can be performed for certain congenital heart defects. Additionally, it plays a role in treating gastric ulcers due to its ability to reduce gastric acid secretion and enhance mucosal protection. Research explores its involvement in inflammation, bone healing, and immune regulation, though therapeutic use in these areas remains experimental.
