title: [Fundamental and clinical evaluation of ceftriaxone in the field of obstetrics and gynecology].
abstract: Ceftriaxone (Ro 13-9904, CTRX), a newly developed third-generation cephem antibiotic, reportedly has an antibacterial spectrum of wide-range and shows a much greater activity than cefazolin especially against Gram-negative bacteria and satisfactory effectiveness against anaerobes. In the gyneco-obstetric infections, the relation between the level in the intrapelvic organs and MIC is an important subject in many respects. The levels in the blood and each tissue determined in 54 cases, as presented in Fig. 2, show that a high concentration can be maintained for a long time. In particular the half-life time in the uterine artery and cubital vein was 8.2 hours and 7.8 hours, respectively, which was longer than that of any other existing antibiotics. This fact suggests that CTRX exhibits sufficient efficacy when administered intravenously even in a small dosage of 1 g in the present study. The clinical efficacy was good or above in all the 7 cases treated. There was neither clinical adverse reaction nor laboratory test abnormality found during and after the administration in any of the 54 cases in the fundamental study and 7 cases in the clinical study. It is suggested from the above-mentioned results that CTRX is an unprecedentedly useful antibiotic with an antibacterial spectrum of wide-range.
