title: Inhibitory effect of cephalosporins on gamma-aminobutyric acid receptor binding in rat synaptic membranes.
abstract: Cephalosporins inhibited gamma-aminobutyric acid receptor binding in a concentration-dependent manner in vitro. Scatchard analysis revealed that cefazolin decreased the binding capacity but did not change the affinity of the receptor. It is suggested that this inhibition of gamma-aminobutyric acid receptor binding may be involved in the induction of convulsions by cephalosporins.
