[Experimental and clinical studies of flomoxef in the field of obstetrics and gynecology. Representative Committee Members of the Research Team for Infections in the Field of Obstetrics and Gynecology].
Flomoxef (FMOX) has a broad antibacterial spectrum against Gram-positive and Gram-negative bacteria; especially its potent antibacterial activity against Staphylococcus aureus is a significant advantage that may not be found with other cephem compounds. In our determination of its antibacterial potency against various clinical isolates obtained from clinical materials (amniotic fluid, intrauterine secretions, exudates of the pelvic dead space) of patients with various infections, we obtained results representing specific features of this drug. From the results, the drug may be expected to produce an excellent effect in the treatment of various infections. Our study on drug concentrations in body fluids and genital tissues demonstrated a good transfer of this drug into various tissues; in every tissue examined, the drug administered by the usual method in the usual dose yielded a concentration exceeding MIC for principal pathogens, thus promising a good clinical response. Indeed a high clinical efficacy rate of 90.1% (good to very good responses) was obtained in a clinical trial involving 222 cases. Administration of the drug in 2 g quantity daily produced a high response rate of 92.8%. It was especially noteworthy that a good response was obtained in 30 of 32 cases (93.8%) in which other cephem compounds had failed. In evaluation of the bacteriological effect, furthermore, the drug showed an excellent rate of bacterial elimination. In conclusion, this drug is expected to be greatly useful in the light of its good transfer into genital tissues and its strong antibacterial activities against Gram-positive cocci, Gram-negative bacteria and anaerobes as well as against multiple bacterial infections predominating among women with genital infections.
