Comparative study of ceftriaxone and aqueous procaine penicillin G in the treatment of uncomplicated gonorrhea in women.

Uncomplicated gonorrhea of 122 mucosal sites in 51 women was successfully treated with either a single intramuscular dose of 250 mg of ceftriaxone (23 patients) or two intramuscular doses of 4.8 X 10(6) U of aqueous procaine penicillin G (28 patients). Women treated with ceftriaxone had 22 cervical, 12 urethral, 10 anal canal, and 5 pharyngeal infections. All 122 pretreatment isolates were inhibited by 0.0125 microgram or less of ceftriaxone per ml. The minimal concentration needed to inhibit 90% of isolates was 0.006 microgram/ml for ceftriaxone and 0.2 microgram/ml for penicillin G. Ceftriaxone was very well tolerated and caused no toxicity.
