[Pharmacokinetic and clinical study on cefodizime in obstetrics and gynecological field].
Clinical investigation of cefodizime (CDZM, THR-221), a newly developed cephem antibiotic, was carried out with regard to its distributions to genital organs, and the drug was evaluated clinically against infections in obstetric and gynecological fields. 1. Distributions to genital organs One gram of CDZM was administered to each patient who received simple total hysterectomy by 1 hour intravenous drip infusion and concentrations of CDZM in genital organs such as antecubital vein, uterine artery, ovary, oviduct, endometrium, myometrium, cervix uteri and portio vaginalis were examined. Serum concentrations were elevated to an average of 90.63 micrograms/ml in 15 minutes after administrations of CDZM and decreased gradually at fixed times. CDZM was distributed in concentration ranges of 45.32-10.96 micrograms/g in ovary, 26.58-10.20 micrograms/g in oviduct, 42.20-9.80 micrograms/g in endometrium, 31.28-11.72 micrograms/g in myometrium, 42.20-12.52 micrograms/g in cervix uteri and 45.32-9.40 micrograms/g in portio vaginalis, and these high concentrations lasted more than 3 hours after administrations. 2. Clinical evaluations CDZM was given to 10 patients, including 7 cases with pelvioperitonitis and 1 case each with pyometra, Bartholin's abscess and puerperal fever, at a dose level of 1 or 2 gram 2 times daily by 30-60 minutes intravenous drip infusion. Overall clinical efficacies were excellent in 3 cases and good in 7 and the efficacy rate was very high, at 100%. Bacteriological efficacies were eradicated in 6 cases, and unknown in 2, and the eradication rate was 100%.(ABSTRACT TRUNCATED AT 250 WORDS)
