Dinoprost tromethamine is the tromethamine (THAM) salt of the naturally occurring prostaglandin F2_alpha. Prostaglandin F2_alpha has several pharmacologic effects on the female reproductive system, including stimulation of myometrial activity, relaxation of the cervix, inhibition of steroidogenesis by corpora lutea, and can potentially lyse corpora lutea.

Dinoprost tromethamine appears to act directly on the myometrium, but this has not been completely established. Dinoprost stimulates myometrial contractions (via its interaction with the prostaglandin receptors) in the gravid uterus that are similar to the contractions that occur in the term uterus during labor. These contractions are usually sufficient to cause abortion. Uterine response to prostaglandins increases gradually throughout pregnancy. Dinoprost also facilitates cervical dilatation and softening.

Non-steroidal chemical compounds with abortifacient activity.

Drugs that stimulate contraction of the myometrium. They are used to induce LABOR, OBSTETRIC at term, to prevent or control postpartum or postabortion hemorrhage, and to assess fetal status in high risk pregnancies. They may also be used alone or with other drugs to induce abortions (ABORTIFACIENTS). Oxytocics used clinically include the neurohypophyseal hormone OXYTOCIN and certain prostaglandins and ergot alkaloids. (From AMA Drug Evaluations, 1994, p1157)
