Cefapirin

Cefapirin is a first generation cephalosporin antibiotic that is broadly effective against gram-negative and gram-positive bacteria. The bactericidal action of cefapirin results from inhibition of cell-wall synthesis, mediated by its binding to penicillin binding proteins. It is mainly used in veterinary medicine for intramammary treatment of mastitis and intrauterine treatment of endometritis in cattle.Formal Name: (6R,7R)-3-[(acetyloxy)methyl]-8-oxo-7-[[(4-pyridinylthio)acetyl]amino]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid.
