Cervidil - General Information
Cervidil, is a naturally occurring prostaglandin E2 (PGE2). It has important effects in labour. It also stimulates osteoblasts to release factors which stimualtes bone resorption by osteoclasts. As a prescription drug it is used as a vaginal suppository, to prepare the cervix for labour and to induce labour.
Pharmacology of Cervidil
Cervidil is equivalent to prostaglandin E2 (PGE2). It stimulates labor and delivery and thus terminates pregnancy. Cervidil is also capable of stimulating the smooth muscle of the gastrointestinal tract of man. This activity may be responsible for the vomiting and/or diarrhea that is not uncommon when dinoprostone is used to terminate pregnancy.
Cervidil for patients
PROSTIN E2 may augment the activity of other oxytocic drugs. Concomitant use with other oxytocic agents is not recommended.
- Hypersensitivity to dinoprostone
- Acute pelvic inflammatory disease
- Patients with active cardiac, pulmonary, renal, or hepatic disease

Cervidil Indication: For the termination of pregnancy from the 12th through the 20th gestational week as calculated from the first day of the last normal menstrual period.

Mechanism Of Action: Cervidil administered intravaginally stimulates the myometrium of the gravid uterus to contract in a manner that is similar to the contractions seen in the term uterus during labor, resulting in the evacuation of the products of conception from the uterus.
