Carboprost (

oxytocic
properties.

Carboprost's main use is in the obstetrical emergency of

postpartum hemorrhage which reduces postpartum bleeding
during these circumstances.

Indication

Used in postpartum hemorrhage caused by uterine atony not controlled by other methods. One study has shown that carboprost tromethamine is more effective than oxytocin in preventing postpartum hemorrhage in high-risk patients undergoing cesarean delivery.[2] Carboprost is also used for the termination of pregnancy in the 2nd trimester.[3]

Contraindication

Contraindicated in severe cardiovascular, renal, and hepatic disease. It is also contraindicated in acute pelvic inflammatory disease. Hypersensitivity to carboprost or any of its components is also a contraindication[3]

Precautions

  • asthma
  • anemia
  • jaundice
  • diabetes mellitus
  • seizure disorders
  • past uterine surgery

Adverse Effects

  • diarrhea (most common, may be sudden in onset)
  • flushing or hot flashes
  • fever
  • chills
  • nausea/vomiting

Storage and Availability

Carboprost is supplied with its salt derivative tromethamine in 1 milliliter ampules containing a 250 microgram/milliliter solution of the active drug. The drug must be refrigerated at a temperature between 2 – 8 degrees Celsius.[3]

Synthesis

A significant deactivating metabolic transformation of natural prostaglandins is enzymatic oxidation of the C-15 hydroxyl to the corresponding ketone. This is prevented, with retention of activity, by methylation to give the C-15 tertiary carbinol series.

Carboprost synthesis:[4][5][6]; G. L. Bundy, U.S. patent 3,728,382 (1973 to Upjohn).

This molecular feature is readily introduced at the stage of the Corey lactone (1) by reaction with methyl Grignard reagent or trimethylaluminium. The resulting mixture of tertiary carbinols (2) is transformed to oxytocic carboprost (3) by standard transformations, including separation of diastereomers, so that the final product is the C-15 analogue. This diastereomer is reputably freeer of prostaglandin side effects than the C-15 (S) isomer.
