Ceforanide: antibacterial activity, pharmacology, and clinical efficacy.
Ceforanide is a new cephalosporin with a longer elimination half-life than any currently available cephalosporin. Its activity is very similar to that of cefamandole, a second-generation cephalosporin, except that ceforanide is less active against most gram-positive organisms. Many coliforms, including Escherichia coli, Klebsiella, Enterobacter, and Proteus, are susceptible to ceforanide, as are most strains of Salmonella, Shigella, Hemophilus, Citrobacter and Arizona species. However, most strains of Serratia marcescens and all Pseudomonas aeruginosa are resistant to this compound. Peak serum concentrations in excess of 100 micrograms/ml are achieved after a 1 g intravenous dose. The elimination half-life of ceforanide is about 3 hrs in patients with normal renal function; this allows twice daily dosing for the majority of patients. As renal excretion amounts for 85-90% of drug elimination, the serum half-life increases to approximately 20 hours in anuric patients. Tissue penetration studies demonstrate inhibitory concentrations in cardiac tissue, bone, and joint fluid. Minor adverse effects have been reported after large doses of ceforanide. Clinical trials indicate that ceforanide is effective in the treatment of skin and soft tissue, pulmonary and urinary tract infections, bone and joint infections, and endocarditis. Ceforanide also has been shown to be as effective as cephalothin or cephaloridine when given prophylactically for vaginal hysterectomy.
