Chemical Properties



Cefoxitin sodium can be used as semi-synthetic antibiotic derived from Cephamycin C, possessing high resistance to β-lactamase inactivation.


An antibiotic derived from Cephamycin C.

brand name

Mefoxin (Merck).

Clinical Use

Cefoxitin (Mefoxin) is a semisynthetic derivative obtainedby modification of cephamycin C, a 7α-methoxy-substitutedcephalosporin isolated independently from variousStreptomyces by research groups in Japan and the UnitedStates. Although it is less potent than cephalothin againstGram-positive bacteria and cefamandole against most of theEnterobacteriaceae, cefoxitin is effective against certainstrains of Gram-negative bacilli (e.g., E. coli, K. pneumoniae,Providencia spp., S. marcescens, indole-positiveProteus spp., and Bacteroides spp.) that are resistant to thesecephalosporins. It is also effective against penicillin-resistantS. aureus and N. gonorrhoeae. The activity of cefoxitin and cephamycins, in general,against resistant bacterial strains is because of their resistanceto hydrolysis by β-lactamases conferred by the 7α-methoxylsubstituent. Cefoxitin is a potent competitive inhibitor ofmany β-lactamases. It is also a potent inducer of chromosomallymediated β-lactamases. The temptation to exploit the β-lactamase–inhibiting properties of cefoxitin by combining itwith β-lactamase–labile β-lactam antibiotics should be temperedby the possibility of antagonism. In fact, cefoxitin antagonizesthe action of cefamandole against E. cloacae andthat of carbenicillin against P. aeruginosa. Cefoxitin aloneis essentially ineffective against these organisms.
The pharmacokinetic properties of cefoxitin resemblethose of cefamandole. Because its half-life is relativelyshort, cefoxitin must be administered 3 or 4 times daily.Solutions of the sodium salt intended for parenteral administrationare stable for 24 hours at room temperature and 1week if refrigerated. 7α-Methoxyl substitution stabilizes, tosome extent, the β-lactam to alkaline hydrolysis.The principal role of cefoxitin in therapy seems to be forthe treatment of certain anaerobic and mixed aerobic–anaerobicinfections. It is also used to treat gonorrhea caused byβ-lactamase–producing strains. It is classified as a secondgenerationagent because of its spectrum of activity.
