CAS 21593-23-7: Cephapirin

Description: Cephapirin is a semisynthetic antibiotic belonging to the cephalosporin class, primarily used for its antibacterial properties. It is effective against a range of Gram-positive bacteria, making it particularly useful in veterinary medicine, especially for treating infections in cattle and other livestock. The chemical structure of Cephapirin includes a beta-lactam ring, which is essential for its antimicrobial activity, as it inhibits bacterial cell wall synthesis. This compound is typically administered via injection and is known for its relatively low toxicity profile. Cephapirin is often utilized in the treatment of mastitis in dairy cows, as well as in other infections where susceptible bacteria are involved. Its pharmacokinetics allow for effective tissue penetration, contributing to its therapeutic efficacy. As with other antibiotics, the potential for resistance development is a concern, necessitating careful use and adherence to veterinary guidelines. Overall, Cephapirin represents an important tool in managing bacterial infections in veterinary practice.
