Cephapirin Sodium（Cat No.:R022998）is a first-generation cephalosporin antibiotic used primarily in veterinary medicine for treating bacterial infections, especially mastitis in dairy cattle. It works by inhibiting bacterial cell wall synthesis, leading to cell lysis and death, and is effective against a range of Gram-positive and some Gram-negative bacteria. Known for its rapid action and stability, Cephapirin Sodium is used as an intramammary infusion to control infections. Its efficacy and low resistance profile make it valuable in studies on antibiotic effectiveness, bacterial resistance, and veterinary health management.
