4.1 Therapeutic Uses

Cephalosporins

GENERAL RANGE OF ACTIVITY & ANTIBACTERIAL SPECTRUM OF CEPHALORIDINE CLOSELY APPROX THAT OF CEPHALOTHIN, ALTHOUGH SOME STRAINS OF E COLI MAY BE SOMEWHAT MORE SENSITIVE TO FORMER. IT ALSO APPEARS TO BE MORE ACTIVE THAN CEPHALOTHIN AGAINST CL PERFRINGENS (WELCHII). MYCOBACTERIUM FORTUITUM IS SENSITIVE TO CEPHALORIDINE...

4.2 Drug Warning

CEPHALORIDINE ACCUM IN BLOOD OF PATIENTS WITH DECR RENAL FUNCTION, & IN AZOTEMIC PATIENTS PLASMA CONCN ARE VERY HIGH; SINGLE DOSE OF 1 G IM YIELDS DETECTABLE CONCN FOR AS LONG AS 4 DAYS. ...CEPHALORIDINE SHOULD NOT BE GIVEN TO SUCH PATIENTS, SINCE IT IS NEPHROTOXIC.

Goodman, L.S., and A. Gilman. (eds.) The Pharmacological Basis of Therapeutics. 5th ed. New York: Macmillan Publishing Co., Inc., 1975., p. 1161

WHILE CEPHALORIDINE PRODUCES LESS IRRITATION /THAN CEPHALOTHIN/, ITS NEPHROTOXICITY OUTWEIGHS THIS ADVANTAGE.

CEPHALORIDINE IS INJECTED EITHER IM OR IV. ... SINCE OTHER, LESS TOXIC CEPHALOSPORINS ARE AVAIL, THERE IS NO REASON TO RECOMMEND THIS PREPN.

5.5 Mechanism of Action

CEPHALOTHIN & ITS CONGENERS INHIBIT BACTERIAL CELL-WALL SYNTHESIS IN MANNER SIMILAR TO THAT OF PENICILLIN. /CEPHALOSPORINS/

Goodman, L.S., and A. Gilman. (eds.) The Pharmacological Basis of Therapeutics. 5th ed. New York: Macmillan Publishing Co., Inc., 1975., p. 1160

Cephaloglycin and cephaloridine are acutely toxic to the proximal renal tubule, in part because of their cellular uptake by a contraluminal anionic secretory carrier and in part through their intracellular attack on the mitochondrial transport and oxidation of tricarboxylic acid (TCA) cycle anionic substrates. Preliminary studies with cephaloglycin have provided evidence of a role of fatty acid (FA) metabolism in its nephrotoxicity, and work with cephaloridine has shown it to be a potent inhibitor of renal tubular cell and mitochondrial carnitine (Carn) transport.
