DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) Section cross-reference(s): 10 Cefpiramide [70797-11-4] was stable to hydrolysis by b-lactamase [9073-60-3]. Cefpiramide inhibited b-lactamase produced by Citrobacter freundii, Enterobacter cloacae, Morganella morganii, and Escherichia coli. Kinetic studies showed that cefpiramide is a competitive inhibitor of cephaloridine hydrolysis by E. cloacae b-lactamase.
