[Fundamental and clinical evaluation of ceftriaxone in the field of obstetrics and gynecology].

Fundamental and clinical evaluation on ceftriaxone (Ro 13-9904, CTRX), a new cephalosporin antibiotic, was performed in the field of obstetrics and gynecology and the following results were obtained. The concentration of CTRX after intravenous injection was determined in the arterial and venous blood, and in the internal genital organs and a favorable tissue transfer was observed. The clinical efficacy rate was not very high (40%); good in 2 out of 5 cases with gyneco-obstetric infections, but it is notable that efficacy was recognized in the case which B. fragilis was detected. Neither adverse reaction nor laboratory test abnormality was seen to be attributable to CTRX in any case.
