B. Segatore et al., IN-VITRO ACTIVITY OF CEFODIZIME (HR-221) IN COMBINATION WITH BETA-LACTAMASE INHIBITORS, Journal of chemotherapy, 5(3), 1993, pp. 147-150
Cefodizime (formerly HR221) was tested either for in vitro microbiolog
ical activity or for its stability to beta-lactamases in the presence
of two beta-lactamase inhibitors (clavulanic acid, tazobactam). Cefodi
zime was a poor substrate of class C enzymes but hyperproducer strains
were generally resistant with or without a beta-lactamase inhibitor u
sed in combination. On the contrary, class A enzymes were able to hydr
olyze cefodizime. However, strains expressing class A beta-lactamase w
ere susceptible to cefodizime in combination with clavulanic acid.
