Curator's Comment: description was created based on several sources, including: https://www.drugs.com/monograph/carboprost-tromethamine.html

Carboprost is an analogue of naturally occurring prostaglandin F2alpha. Administered intramuscularly carboprost stimulates in the gravid uterus myometrial contractions similar to labor contractions at the end of a full term pregnancy. It is indicated for aborting pregnancy between the 13th and 20th weeks of gestation as calculated from the first day of the last normal menstrual period and for the treatment of postpartum hemorrhage due to uterine atony, which has not responded to conventional methods of management. The most frequent adverse reactions observed are related to its contractile effect on smooth muscle: vomiting, diarrhea, nausea, fever and flushing. Carboprost may augment the activity of other oxytocic agents. Concomitant use with other oxytocic agents is not recommended.

HEMABATE is indicated for the treatment of postpartum hemorrhage due to uterine atony which has not responded to conventional methods of management. Prior treatment should include the use of intravenously administered oxytocin, manipulative techniques such as uterine massage and, unless contraindicated, intramuscular ergot preparations. Studies have shown that in such cases, the use of HEMABATE has resulted in satisfactory control of hemorrhage, although it is unclear whether or not ongoing or delayed effects of previously administered ecbolic agents have contributed to the outcome. In a high proportion of cases, HEMABATE used in this manner has resulted in the cessation of life threatening bleeding and the avoidance of emergency surgical intervention. Launch Date 2.84687991E11

Sample Use Guides

In Vivo Use Guide

1. Abortion and Indications 1–4: An initial dose of 1 mL of HEMABATE Sterile Solution (containing the equivalent of 250 micrograms of carboprost) is to be administered deep in the muscle with a tuberculin syringe. Subsequent doses of 250 micrograms should be administered at 1½ to 3½ hour intervals depending on uterine response. An optional test dose of 100 micrograms (0.4 mL) may be administered initially. The dose may be increased to 500 micrograms (2 mL) if uterine contractility is judged to be inadequate after several doses of 250 micrograms (1 mL). The total dose administered of carboprost tromethamine should not exceed 12 milligrams and continuous administration of the drug for more than two days is not recommended. 2. For Refractory Postpartum Uterine Bleeding: An initial dose of 250 micrograms of HEMABATE Sterile Solution (1 mL of HEMABATE) is to be given deep, intramuscularly. In clinical trials it was found that the majority of successful cases (73%) responded to single injections. In some selected cases, however, multiple dosing at intervals of 15 to 90 minutes was carried out with successful outcome. The need for additional injections and the interval at which these should be given can be determined only by the attending physicians as dictated by the course of clinical events. The total dose of HEMABATE should not exceed 2 milligrams (8 doses).

Route of Administration: Intramuscular

In Vitro Use Guide

The pEC50 values obtained for carboprost (as a measure of potency) on 146 myometrial strips from 19 donors, in relation to the two contractile parameters (the maximum amplitude (MAMP) and the mean contractile force above baseline (MCF)) were 6.0 for MAMP and 5.8 for MCF.
