4 Drug and Medication Information
4.1 Drug Indication

Used for aborting second-trimester pregnancy (between the twelfth to eighteenth week of gestation) and in incomplete abortion or for therapeutic abortion in cases of intrauterine fetal death and congenital abnormalities incompatible with life. Also used at low-doses for medically indicated induction of labor at term. Also injected intra-arterially for use as a vasodilator to assist in angiography.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Dinoprost tromethamine is the tromethamine (THAM) salt of the naturally occurring prostaglandin F2alpha. Prostaglandin F2alpha 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.


5.2 MeSH Pharmacological Classification

Abortifacient Agents, Nonsteroidal

Non-steroidal chemical compounds with abortifacient activity. (See all compounds classified as Abortifacient Agents, Nonsteroidal.)


Oxytocics

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) (See all compounds classified as Oxytocics.)


5.3 Absorption, Distribution and Excretion

Absorption

Slowly absorbed from the amniotic fluid into systemic circulation.


5.4 Metabolism/Metabolites

Enzymatic dehydrogenation primarily in the maternal lungs and also in the liver.


5.5 Biological Half-Life

The half-life of dinoprost in amniotic fluid is 3 to 6 hours. The plasma half-life of dinoprost after intravenous administration is reported to be less than 1 minute.


5.6 Mechanism of Action

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.
