[Clinical studies on excretion in biliary tract with the antibiotic cefotiam].
Cefotiam (CTM) was administered through 1 hour intravenous drip infusion for the patients performed biliary tract surgery. The concentration of CTM in serum, gallbladder tissue and the excretion in bile of the choledochus were measured. Twenty-one patients performed cholecystectomy were followed the concentration of CTM in the gallbladder tissue and the results were studied with pharmacokinetic analysis. The simulation curve, which was described by computer system in two-compartment open model, showed the maximal concentration of CTM in the serum was 60.3 micrograms/ml at 1 hour after infusion and that in the gallbladder tissue was 27.1 micrograms/g at 1.07 hours. The concentration of CTM in the gallbladder tissue was presumed to be in proportion to that of CTM in the serum. Six patients performed bile drainage were followed the concentration of CTM in bile of the choledochus for 6 hours after infusion. The maximal concentration was 215.2 +/- 62.7 micrograms/ml at 3 hours after injection, and the mean biliary recovery was 1.66 +/- 0.55% through 6 hours. Neither any side effects nor any abnormal values in the laboratory analysis of samples were observed for CTM.
