The in vitro effects of ceftibuten on human polymorphonuclear leukocyt
e (PMN) chemotaxis, phagocytosis and chemiluminescence were investigat
ed. PMN from healthy adult donors were incubated for 1 h in medium alo
ne or in medium containing increasing concentrations of ceftibuten (4,
8 and 40 times the MIC for Escherichia coli). Up to 40 MIC ceftibuten
did not significantly interfere with the function of PMN.
