    Cephapirin benzathine

    Cephapirin is a first-generation cephalosporin that boasts broad spectrum activity against gram-positive and gram-negative organisms. It is more resistance to beta-lactamases than the penicillin family. It is commonly used in the veterinary field.

    Cephapirin benzathine is practically insoluble in water, ether, and toluene.
    Mechanism of ActionLike β-lactams, cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death.
