Enoxacin is a broad-spectrum 6-fluoronaphthyridinone antibacterial agent. Target: antibacterial Enoxacin is a new quinolone carboxylic acid compound. Its activity against 740 bacterial isolates was determined. It inhibited 90% Escherichia coli, Klebsiella sp., Aeromonas sp., Enterobacter spp., Serratia spp., Proteus mirabilis, and Morganella morganii at less than or equal to 0.8 micrograms/ml [1]. Daily plasma theophylline concentrations were measured in 14 patients. The mean +/- s.d. theophylline concentrations increased from 8.5 +/- 2.8 micrograms ml-1 prior to enoxacin to a maximum of 21.7 +/- 7.8 micrograms ml-1 during coadministration [2].
