[Efficacy of ceftriaxone against gynecoobstetric infections].

Ceftriaxone (Ro 13-9904, CTRX), a newly developed parenteral cephalosporin antibiotic was clinically evaluated in gynecoobstetric infections and the following results were obtained. CTRX was administered by intravenous drip infusion twice a day in a daily dose of 2 to 4 g to 10 cases with gynecoobstetric infections, consisting of 8 with intrauterine infections, 1 with adnexitis and 1 with infection of external genitalia. The global clinical efficacy was excellent in 2 and good in 6 out of 8 cases with intrauterine infections, and in 2 others, the efficacy rate being 100%. Bacteriologically, the eradication of bacteria was observed in 5, unchange in 2 and alternation of bacteria in 2 among 9 cases where the causative strains were detected. Neither adverse reaction nor laboratory test abnormality was observed. The above-mentioned results suggest that CTRX is a highly safe antibiotic expected to be excellent in the clinical efficacy and bacteriological effects.
