The cephalosporins are eliminated by both glomerular filtration and tubular excretion. Chronic administration of cephalosporins may cause renal tubular necrosis. Cefotaxime is a new semisynthetic cephalosporin antibiotic with an unusually broad antibacterial spectrum. Therefore, to determine whether any variations at plasma protein binding with furosemide by cefotaxime were responsible for its diuretic action of urine volume and electrolytes in rabbits, author studies effects on drug-interaction of cefotaxime and furosemide. The following results were obtained. 1. The group, administrated simultaneously furosemide and cefotaxime, was significantly increased compared with furosemide alone group on the urine volume, urinary electrolytes, because markedly increased the inhibition of Na^+ and Cl^- reabsorption in the renal tubule, and glomerular filtration rate without any differences. 2. Serum concentration of cefotaxime in rabbits was significanly elevated by the combination with furosemide, and markedly inhibited the elimination levels of cefotaxime in urine of rabbits. Conclusion of above results; Synergistic effect of cefotaxime on diuretic action of furosemide showed the comparative inhibition of plasma protein binding with furosemide by cefotaxime, and the continuation of diuretic effect seems excretion of furosemide on the in-hibited by competition between furosemide and cefotaxime in renal tubular excretion.
