    Abstract:
    Tissue transfer and clinical effects of imipenem/cilastatin sodium (MK-0787/MK-0791), a new carbapenem antibiotic, were studied and the following results were obtained. Penetrations of MK-0787 into uterine arterial blood and into pelvic dead space exudate were good. When MK-0787/MK-0791 was administered at a dose of 500 mg/500 mg by a 30-minute intravenous drip infusion, the peak level of MK-0787 in uterine arterial blood was 22.2 micrograms/ml, 30 minutes after the completion of the drip infusion. The peak level of MK-0787 in pelvic dead space exudate was 12.9 micrograms/ml at 2 hours and it dropped to 2.6 micrograms/ml at 6 hours. MK-0791 levels were similar to those of MK-0787. Penetrations of MK-0787 into tissues were also good. When MK-0787/MK-0791 was administered at a dose of 500 mg/500 mg by a 30-minute intravenous drip infusion, the level of MK-0787 was 2.2 +/- 1.1 micrograms/g in the oviduct, 2.7 +/- 2.1 micrograms/g in the ovary, 2.5 +/- 1.2 micrograms/g in the endometrium, 3.0 +/- 1.6 micrograms/g in the myometrium, 3.1 +/- 1.9 micrograms/g in the cervix uteri and 3.8 +/- 2.0 micrograms/g in the portio vaginalis at 1 hour after administration. These levels were reduced to halves, respectively, in approximately 2 hours. Four patients with intrauterine infections and 2 with vaginal stump infections were treated with MK-0787/MK-0791 at a daily dose of 1 g/1 g (500 mg/500 mg X 2). Good clinical and bacteriological responses were observed in 5 patients and causative organisms were eradicated in 2 patients.(ABSTRACT TRUNCATED AT 250 WORDS)
