Misoprostol: pharmacokinetic profiles, effects on the uterus and side-effects

Int J Gynaecol Obstet. 2007 Dec;99 Suppl 2:S160-7. doi: 10.1016/j.ijgo.2007.09.004. Epub 2007 Oct 26.


Misoprostol, a synthetic prostaglandin E1 analogue, is commonly used for medical abortion, cervical priming, the management of miscarriage, induction of labor and the management of postpartum hemorrhage. It can be given orally, vaginally, sublingually, buccally or rectally. Studies of misoprostol's pharmacokinetics and effects on uterine activity have demonstrated the properties of the drug after various routes of administration. These studies can help to discover the optimal dose and route of administration of misoprostol for individual clinical applications. Misoprostol is a safe drug but serious complications and teratogenicity can occur with unsupervised use.
