Description: Cefotetan is comparatively stable, lasting for approximately 24 hours at room temperature when reconstituted. Slight yellowing and slight darkening produce materials that are still acceptable for therapy. Cefotetan is chemically incompatible with tetracycline, aminoglycosides, and with heparin, often forming precipitates with them. With respect to its molecular mode of action, it has a special affinity for PBP-3 of Gram-negative bacteria, consequently producing filamentous forms. It also binds well with PBP-1A and -1B,therefore leading to cell lysis and death. Whereas it is stable to a wide range of lactamases, it also is a potent inducer in some bacteria.
Cefotetan disodium is an antibiotic related to Cephalosporin, used in the treatment of bacterial infections.
