title: Inhibitory activity of cefpiramide on beta-lactamase.
abstract: The beta-lactamase stability and inhibitory activity of cefpiramide were investigated. Cefpiramide was found to be stable to hydrolysis and inhibited beta-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 beta-lactamase.
