The transfer to cerebrospinal fluid of a new oxacephem
antibiotic flomoxef (FMOX, 6315-S) and its clinical efficacy against
bacterial infections were investigated. 1. In 3 cases of purulent
meningitis, cerebrospinal fluid concentrations of FMOX after one shot
intravenous injection of 100 mg/kg during the acute stage of
infections were 5.12-6.32 micrograms/ml and ratios of FMOX in cerebrospinal fluid in serum were about 5%. During the recovery stage, cerebrospinal fluid concentrations were about 3.8 micrograms/ml and cerebrospinal fluid/serum ratios were about 3.5%. 2. In 1 case of purulent
meningitis, the treatment with FMOX was clinically effective but this case was classified as "unevaluable" because other
drug was used concomitantly. FMOX was rated effective in other 2 cases of purulent
meningitis. Of 9 cases of
pneumonia, FMOX was rated very effective in 8 cases and it was rated only effective in the other. Of 4 cases of
bronchitis, the
drug was rated very effective in 3 cases and only effective in the other. FMOX was rated very effective against 2 cases of
tonsillitis, also. 3. As side effects,
thrombocytosis was observed in 3 of 20 cases examined. All cases, however, were deemed unrelated to the FMOX treatment and the side effect was only transient as are often found in courses of recovery from
infections.
