title: [Cefpiramide: antibacterial activity, pharmacokinetics, and clinical evaluation].
abstract: We determined MIC values of cefpiramide (CPM) against clinical isolates from 100 patients who were subjected to total hysterectomy between April 1986 and March 1988. We also investigated the concentrations of CPM in uterine tissue and assessed the clinical efficacy of postoperative prophylaxis. 1. Against bacteria isolated from clinical materials the MIC80 values of CPM were as follows: Staphylococcus epidermidis 1.56 micrograms/ml, Enterococcus faecalis 25 micrograms/ml, and Escherichia coli 6.25 micrograms/ml. 2. Peak concentrations of CPM in various tissues and tissue/serum ratios of AUC were as follows: cervix uteri 35 micrograms/g (39.5%), perimetrium 43 micrograms/g (44.9%), endometrium 39 micrograms/g (51.6%), myometrium 28 micrograms/g (26.8%), oviduct 67 micrograms/g (41.9%), and ovary 27 micrograms/g (45.8%). In all tissues examined CPM concentrations were above 4 micrograms/g after 600 minutes. 3. Serum half-lives were T 1/2(alpha) = 13.2 minutes and T 1/2(beta) = 260.2 minutes. 4. The efficacy rate in postoperative prophylaxis was 97.9%. 5. No serious side effects were observed.
