Abstract

A total of 74 men and 26 women with uncomplicated gonorrhoea were treated with ceftizoxime sodium 0.5 g intramuscularly. The cure rate was 99% and included successful treatment of four infections due to beta-lactamase producing organisms. The minimum inhibitory concentrations (MICs) of ceftizoxime in vitro were very much lower than those of penicillin and cefuroxime, and side effects were minimal. We conclude that ceftizoxime is effective against Neisseria gonorrhoeae in vivo and in vitro.
