Final answer:
Misoprostol is a prostaglandin analogue used in obstetrics and gynecology for various purposes, including labor induction and abortion. It works by binding to specific receptors in the uterus and causing contractions. Some major contraindications include allergies to the medication and history of uterine rupture.
Step-by-step explanation:
Misoprostol is a medication classified as a prostaglandin analogue. It is commonly used in obstetrics and gynecology to induce labor, manage miscarriages, and perform abortions.
The mechanism of action of misoprostol involves binding to specific receptors in the uterus, which leads to increased contractions and softening of the cervix. This helps in the expulsion of the fetus or the management of miscarriage.
Some indications for misoprostol include labor induction, medical abortion, management of incomplete abortion or miscarriage, and prevention and treatment of postpartum hemorrhage.
Major contraindications for misoprostol include a known allergy to the medication, history of cesarean delivery, history of uterine rupture, and conditions that may contraindicate the use of uterine contractions, such as placenta previa.
Common adverse effects of misoprostol include abdominal cramps, nausea, vomiting, diarrhea, and fever. It is crucial to use misoprostol under medical supervision to ensure its safe and effective use.
