Carboprost (INN, trade names for the tromethamine salts Hemabate, Tham) is a synthetic prostaglandin analogue of PGF2α (specifically, it is 15-methyl-PGF2α) with oxytocic properties. Carboprost 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. Carboprost is also used for the termination of pregnancy in the 2nd trimester.Unlabeled use:

Hemorrhagic Cystitis
PID

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 Exert caution in asthmatic patients as carboprost may cause bronchospasm. 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. 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. This molecular feature is readily introduced at the stage of the Corey lactone (1) by reaction with methyl Grignard reagent or trimethylaluminium.
Its appearance is similar to a loose flap of skin that might occur if the cat had been overweight and had then lost weight. It provides a little extra protection against kicks, which are common during cat fights as a cat will try to rake with its rear claws. In wild cats, the ancestors of domesticated felines, this pouch appears to be present to provide extra room in case the animal has the opportunity to eat a large meal and the stomach needs to expand. This stomach pouch also allows the cat to bend and expand, allowing for faster running and higher jumping. Skeleton
Cats have seven cervical vertebrae like almost all mammals, thirteen thoracic vertebrae (humans have twelve), seven lumbar vertebrae (humans have five), three sacral vertebrae (humans have five because of their bipedal posture), and, except for Manx cats and other shorter tailed cats, twenty-two or twenty-three caudal vertebrae (humans have three to five, fused into an internal coccyx). The extra lumbar and thoracic vertebrae account for the cats enhanced spinal mobility and flexibility, compared to humans. The caudal vertebrae form the tail, used by the cat as a counterbalance to the body during quick movements. Between their vertebrae, they have elastic discs, useful for cushioning the jump landings. Unlike human arms, cat forelimbs are attached to the shoulder by free-floating clavicle bones, which allows them to pass their body through any space into which they can fit their heads.
