Cefamandole nafate is a formate ester prodrug form of the cephalosporin antibiotic cefamandole .1 Cefamandole nafate inhibits the growth of E. cloacae, E. coli, K. pneumoniae, P. mirabilis, P. vulgaris, P. morganii, S. aureus, and S. pyogenes in vitro (MICs = 0.1-50 μg/ml). In vivo, cefamanadole nafate protects against E. cloacae, E. coli, K. pneumoniae, P. mirabilis, P. vulgaris, P. morganii, S. aureus, and S. pyogenes infection in mice (ED50s = 0.3-334 mg/kg). Cefamandole (500 mg/kg) also protects against nephrotoxicity induced by the aminoglycoside antibiotic tobramycin in rats.2
