Comparative study of cefoperazone and spectinomycin for treatment of uncomplicated gonorrhea in men.

Beta-lactamase-negative Neisseria gonorrhoeae infections were treated with single-dose cefoperazone (0.5 or 1.0 g) or spectinomycin (2.0 g). Anogenital infections were cured in 36 (83%) of 43 volunteers given 0.5 g of cefoperazone, 61 of 61 volunteers given 1.0 g of cefoperazone, and 99 of 100 volunteers given spectinomycin. The cefoperazone geometric mean MIC for 242 isolates was 0.028 microgram/ml. Cefoperazone (1.0 g) and spectinomycin (2.0 g) are comparable for the therapy of anogenital gonorrhea in men.
