One hundred sixteen patients (92 men and 24 women) with suspected uncomplicated gonorrhea were randomized in a double-blind manner to receive intramuscular treatment with 1.0 g of cefpimizole, 1.0 g of cefotaxime, or 4.8 x 10(6) units of aqueous procaine penicillin G (APPG) with 1 g of oral probenecid. Seventeen percent were nonassessable (cultures negative, co-existing syphilis, etc.). Infection sites in 96 assessable patients were urethra (78), cervix (17), pharynx (two), and rectum (two). Of 52 patients treated with cefpimizole, 46 (88%) were bacteriologically cured, as compared with 100% (24 of 24) treated with APPG (P = 0.18) and 90% (18 of 20) treated with cefotaxime (P greater than 0.20). On a weight basis the in-vitro activity of cefpimizole against Neisseria gonorrhoeae was similar to that of APPG. Pain at the injection site was reported by 52% of patients treated with cefpimizole as compared with 27% of those given cefotaxime (P = 0.008) and 17% of those given APPG (P = 0.002). No major organ toxicity was found with cefpimizole, cefotaxime, or APPG. Thus, for acute uncomplicated gonorrhea cefpimizole is similar in efficacy to cefotaxime and APPG but has a higher frequency of pain at the injection site.
