The authors have carried out the pharmacokinetic and clinical studies of cefminox (CMNX, MT-141). The results were as follows: CMNX was given by intravenous drip infusion for 1 hour at a dose of 20 mg/kg b.w. to 2 children. The serum levels of CMNX were 103.02 micrograms/ml and 77.73 micrograms/ml at 1 hour after drip infusion, and the levels at 7 hours were 4.39 micrograms/ml and 4.19 micrograms/ml, respectively. The half life times were 1.20 hours and 1.32 hours, respectively. CSF concentrations of CMNX at 1 hour after drip infusion of a dose of 50 mg/kg in 3 patients with aseptic meningitis were 1.68 micrograms/ml (d.i. for 30 minutes), less than or equal to 0.25 micrograms/ml (d.i. for 1 hour) and 0.51 micrograms/ml (d.i. for 1 hour), respectively. CSF/serum ratios were 1.1% and 0.6%. Clinical efficacy was evaluated in 10 cases with purulent tonsillitis (3 cases), pneumonia (3 cases), pyelonephritis (1 case) and enteritis (3 cases). Excellent and good responses were obtained in all cases. Bacteriological response in the form of eradication was noted 8 of 9 cases. No side effects were observed. |
