CAS#: 117467-28-4 (pivoxil)

Description: Cefditoren Pivoxil is a semi-synthetic, broad-spectrum, beta-lactamase resistant, third-generation cephalosporin antibiotic with bactericidal activity. Cefditoren pivoxil is a prodrug that is rapidly hydrolyzed by intestinal esterases during absorption to the microbiologically active cefditoren, an active aminothiazolyl cephalosporin. Cefditoren inactivates penicillin binding proteins (PBPs) thereby interfering with peptidoglycan synthesis and inhibiting bacterial cell wall synthesis.
