    Abstract:
    Ceftazidime (CAZ), a new cephalosporin antibiotic, was studied in the field of obstetrics and gynecology, and the following results were obtained. The absorption and tissue penetration of CAZ into intrapelvic genital organs were good after a single drip infusion of 1.0 g for 30--60 minutes. The maximum level of 76.4 micrograms/ml was obtained in uterine artery serum at 8 minutes after administration. The high concentrations were also obtained in genital tissues; the maximum concentrations ranged from 46.8--62.1 micrograms/g at 20 minutes after administration and the levels were as high as 2.1--7.7 micrograms/g at 5 hours and 40 minutes after administration. The concentration curves in tissues were consistent with those of serum levels. The concentrations of CAZ in retroperitoneal dead space exudate were determined after intravenous drip infusion of 1 g. The peak levels ranged from 26 to 32 micrograms/ml after 30 minutes of administration and the level of 8.53 micrograms/ml was sustained even 6 hours later. Good response was obtained in cases of gyneco-obstetric infections such as intrauterine infection, intrapelvic infection and external genital infection with daily dose of 2--4 g. CAZ was effective in 13 out of 14 cases (the efficacy ratio; 92.9%). As to side effects, gastric discomfort and vomiting were observed in 1 case.
