[Clinical application of latamoxef during the perinatal period]

Pharmacokinetic studies and clinical evaluations of latamoxef (LMOX) were carried out in perinatal mothers and infants. LMOX was promptly absorbed after intravenous injection and intravenous drip infusion in pregnant women, producing dose-related peak blood levels. Placental transference to the fetus was favorable. After intravenous injection and intravenous drip infusion of 1.0--2.0 g of LMOX, drug concentration of the cord blood, amniotic fluid and fetal blood exceeded MICs of the main pathogenic organisms. By administration of the dose of 1.0--2.0 g twice a day, it is possible to successfully prevent or treat uterine infections. LMOX was effective in the prophylaxis or therapy of perinatal infections. Moreover, newborn infants delivered from mothers receiving LMOX treatment having drug concentrations exceeded MICs of main pathogenic organisms however not remained more than 12 hours after birth, and did not exhibit any laboratory test abnormalities. The above results demonstrated that LMOX is a clinically useful antibiotic for the prophylaxis and treatment of perinatal infections.
