    Abstract:
    Fundamental and clinical studies on aztreonam (AZT), a new synthetic monobactam antibiotic, were performed and following results were obtained. Concentration of AZT was examined in serum, internal genital tissues and retroperitoneal fluid after a single intravenous administration of 1 g dose. The venous serum level of AZT was 114.0 micrograms/ml at 10 minutes after the administration, then decreased to 7.0 micrograms/ml at 3 hours. Since concentration of AZT in examined tissues showed wide variation, it was irrelevant to calculate transfer ratio. Concentration in retroperitoneal fluid made the peak of 40.0 +/- 22.6 micrograms/ml at 1 hour after the administration, then slowly decreased to 13.4 +/- 3.2 micrograms/ml at 6 hours. Judging from above data, the transfer of AZT to retroperitoneal fluid was favorable. In clinical trial, AZT was given to 17 cases with obstetrical and gynecological infections such as endometritis, uterine adnexitis, pelvic peritonitis, parametritis and lymphocystitis. The efficacy was evaluated as excellent in 2 cases, good in 12 and poor in 3, and efficacy rate was 82.4%. No side effects were observed in any of the cases. In laboratory findings, transient elevation of liver function in 2 cases and eosinophilia in 1 case were noticed.
