A first-generation cephalosporin antibiotic, it is effective against gram-negative and gram-positive organisms. Being more resistant to beta-lactamases than penicillins, it is effective agains most staphylococci, though not methicillin-resistant staphylococci. It has a role as an antibacterial drug. It is a cephalosporin and an organic sodium salt. It contains a cephapirin(1-)."}]
