What are the uses of this medicine?

Carboprost (Hemabate) is used for aborting pregnancy between the 13th and 20th weeks of gestation. Carboprost is used in the following conditions related to second trimester abortion:

• Failure of expulsion of the fetus during the course of treatment by another method;
• Premature rupture of membranes in intrauterine methods with loss of drug and insufficient or absent uterine activity;
• Requirement of a repeat intrauterine instillation of drug for expulsion of the fetus;
• Inadvertent or spontaneous rupture of membranes in the presence of a previable fetus and absence of adequate activity for expulsion.

• Carboprost is indicated for the treatment of postpartum hemorrhage due to uterine atony which has not responded to conventional methods of management.
• Carboprost's main use is in the obstetrical emergency of postpartum hemorrhage which reduces postpartum bleeding during these circumstances.

How does this medicine work?

• The tromethamine salt of the (15S)-15 methyl analogue of naturally occurring prostaglandin F2 alpha (PGF2 alpha) with oxytocic activity.
• Mimicking endogenous PGF2 alpha, carboprost activates prostaglandin F receptor, a G-protein coupled receptor, on smooth muscle cells, thereby resulting in smooth muscle contractions.
• When administered intramuscularly on gravid subjects, this agent induces myometrium contractions, thereby initiating luteolysis and consequently parturition.
• Furthermore, carboprost's action on vascular smooth muscle and gastrointestinal tract sphincters leads to raised blood pressure and induces vomiting or diarrhea, respectively.
