Uses for Carboprost Tromethamine Termination of Pregnancy Termination of intrauterine pregnancy during the second trimester (weeks 13 20 of gestation, dated from the first day of the last menstrual period). 1 14 15 16 Used after failure of another method (e.g., in the event of premature rupture of membranes with loss of hypertonic abortifacients accompanied by inadequate uterine activity, when repeated intra-amniotic drug administration needed to expel fetus); used to induce abortion after membrane rupture. 1 Postpartum Hemorrhage Treatment of postpartum hemorrhage in the presence of uterine atony that has not responded to usual therapy (i.e., IV oxytocin, uterine massage, IM ergot alkaloids [unless contraindicated]). 1 8 9 10 12 13 20 Carboprost Tromethamine Dosage and Administration General To minimize adverse GI effects, consider pretreatment use or concurrent administration of antiemetic and antidiarrheal agents. 1 14 15 Administration IM Administration Administer by deep IM injection. 1 For postpartum hemorrhage, has been administered directly into the uterine corpus . 8 Dosage Available as carboprost tromethamine; dosage is expressed in terms of carboprost. 1 Closely adhere to recommended dosage. 1 Dosage determined by uterine response. 1 Adults Termination of Pregnancy IM Initially, 250 mcg. 1 15 Alternatively, initiate with test dose of 100 mcg. 1 15 Subsequently, 250 mcg at 1.5- to 3.5-hour intervals depending on uterine response. 1 15 After several 250-mcg doses, may increase dose to 500 mcg if uterine contractility is inadequate. 1 15 Maximum total dose is 12 mg. 1 Postpartum Hemorrhage IM Initially, 250 mcg; repeat every 15 90 minutes up to a maximum total dose of 2 mg. 1 8 10 Single dose usually adequate. 1 13 20 Clinician should determine the need for additional doses and dosing interval based on clinical events. 1 Prescribing Limits Adults Termination of Pregnancy IM Maximum total dose is 12 mg; continuous administration for >2 days not recommended. 1 Postpartum Hemorrhage IM Maximum total dose is 2 mg. 1 Cautions for Carboprost Tromethamine Contraindications Known hypersensitivity to carboprost. 1 Acute pelvic inflammatory disease. 1 Active cardiac, pulmonary, renal, or hepatic disease. 1 Warnings/Precautions Warnings Administer by qualified professional personnel in a hospital where intensive care and surgical facilities are immediately available. 1 Considerations in Patients Undergoing Termination of Pregnancy Carboprost does not affect the fetoplacental unit. 1 Possibility exists that a previable fetus could exhibit transient signs of life following carboprost-induced abortion; carboprost is not indicated if the fetus has reached the stage of viability. 1 If the pregnancy is not terminated with carboprost, complete abortion using another method. 1 Risk of cervical trauma; examine each patient for cervical injuries after abortion is complete. 1 14 Caution in patients with a compromised (scarred) uterus. 1 Benzyl Alcohol in Neonates Carboprost tromethamine injection contains as a preservative benzyl alcohol, which has been associated with toxicity (fatalities) in neonates. 1 (See Pediatric Use under Cautions.) General Precautions Musculoskeletal Effects Proliferation of long bones reported in neonates receiving long-term therapy with alprostadil (prostaglandin E 1 ). 1 22 No evidence that short-term administration of carboprost has similar effects on bone. 1 Concomitant Diseases Caution in patients with history of asthma, seizure disorders, diabetes, or anemia. 1 24 Fever Transient fever (i.e., temperature elevations >1.1 C) reported in approximately 12.5% of patients. 1 When used for termination of pregnancy, may be difficult to distinguish drug-induced temperature elevations from post-abortion endometritis. 1 Cardiovascular Effects Increased BP reported. 1 13 20 Increase in BP was observed in 4% of women receiving the drug for postpartum hemorrhage in 1 study; specific treatment for hypertension was not needed. 1 13 Caution in patients with hypertension, hypotension, or cardiovascular disease. 1 Chorioamnionitis Chorioamnionitis may contribute to postpartum uterine atony and hemorrhage; individuals with chorioamnionitis experiencing postpartum hemorrhage have failed to respond to carboprost. 1 8 9 10 12 13 Specific Populations Pregnancy Category C. 1 Pediatric Use Not indicated in pediatric patients. 1 Large amounts of benzyl alcohol (i.e., 100 400 mg/kg daily) have been associated with toxicity (fatal gasping syndrome ) in neonates; 1 2 3 4 5 6 7 each mL of carboprost tromethamine injection contains 9.45 mg of benzyl alcohol. 1 Hepatic Impairment Caution in patients with hepatic disease, including jaundice. 1 Contraindicated in patients with active hepatic disease. 1 Renal Impairment Caution in patients with renal disease. 1 Contraindicated in patients with active renal disease. 1 Common Adverse Effects Vomiting, 1 10 14 15 18 20 diarrhea, 1 10 13 14 15 18 nausea, 1 13 20 fever, 1 20 flushing. 1 14 15 Interactions for Carboprost Tromethamine May increase activity of other oxytocic agents; concomitant use not recommended. 1 Carboprost Tromethamine Pharmacokinetics Absorption Bioavailability Rapidly absorbed following IM administration; peak plasma concentrations attained in 20 30 minutes. 1 11 21 Onset When used for postpartum hemorrhage, increase in uterine tone and decreased bleeding noted after about 45 minutes. 13 Elimination Metabolism Metabolized principally via ω-oxidation and to limited extent via ω-oxidation to a number of metabolites. 19 Metabolized more slowly than naturally occurring prostaglandin F 2α . 11 15 17 19 21 Elimination Route Excreted in urine (83%), mainly as metabolites. 19 Stability Storage Parenteral Injection 2 8 C. 1 Actions Elicits pharmacologic responses usually produced by endogenous prostaglandin F 2α ; more potent and has longer duration of activity on the uterus than prostaglandin F 2α . 15 17 18 Increases the amplitude and frequency of uterine contractions throughout pregnancy; uterine response to the drug increases with the duration of pregnancy. 23 After delivery, uterine contractions impede uterine blood flow. 1 Produces cervical dilation. 15 Produces contraction of vascular smooth muscle; may result in increased BP. 1 10 20 Causes stimulation of the smooth muscle of the GI tract, increasing GI motility. 1 18 Stimulates transient bronchoconstriction in some patients. 1 12 Advice to Patients Importance of women informing clinicians if they plan to breast-feed. 1 Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses. 1 Importance of informing patients of other important precautionary information. 1 (See Cautions.)
