Sourced from openFDAMechanism-of-action class: Prostaglandin Receptor Agonists.
Indications
Sourced from openFDA- Carboprost tromethamine injection, USP 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 in the following conditions related to second trimester abortion: 1. Failure of expulsion of the fetus during the course of treatment by another method; 2.
Contraindications
Sourced from openFDA- 1. Hypersensitivity (including anaphylaxis and angioedema) to carboprost tromethamine injection Sterile Solution [ see ADVERSE REACTIONS, Post-marketing Experience ] 2.contraindicated
Dosage & administration
Sourced from openFDA1. Abortion and Indications 1-4 An initial dose of 1 mL of carboprost tromethamine injection 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 Bleedin g: An initial dose of 250 micrograms of carboprost tromethamine injection sterile solution (1 mL of carboprost tromethamine injection) 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 carboprost tromethamine injection should not exceed 2 milligrams (8 doses).
Adverse reactions
Sourced from openFDAThe adverse effects of carboprost tromethamine sterile solution are generally transient and reversible when therapy ends. The most frequent adverse reactions observed are related to its contractile effect on smooth muscle. In patients studied, approximately two-thirds experienced vomiting and diarrhea, approximately one-third had nausea, one-eighth had a temperature increase greater than 2° F, and one-fourteenth experienced flushing. The pretreatment or concurrent administration of antiemetic and antidiarrheal drugs decreases considerably the very high incidence of gastrointestinal effects common with all prostaglandins used for abortion. Their use should be considered an integral part of the management of patients undergoing abortion with carboprost tromethamine. Of those patients experiencing a temperature elevation, approximately one-sixteenth had a clinical diagnosis of endometritis. The remaining temperature elevations returned to normal within several hours after the last injection.
Use in specific populations
Sourced from openFDAPregnancy: Teratogenic Effects: Animal studies do not indicate that carboprost tromethamine is teratogenic, however, it has been shown to be embryotoxic in rats and rabbits and any dose which produces increased uterine tone could put the embryo or fetus at risk.
