Pseudomonas keratitis is difficult to treat and aminoglycosides, the drugs now used for this purpose, are not always effective. New drugs are thus needed to cure gentamicin resistant pseudomonas ocular infections. Enoxacin, a new quinolone, active in vitro against Pseudomonas aeruginosa, was evaluated in experimental ulcerative keratitis produced by a gentamicin resistant isolate of Pseudomonas aeruginosa in rabbits. Our study shows that enoxacin eye drops eliminated pseudomonas infection of the cornea and achieved therapeutic levels in the aqueous humor. Supplementation with parenterally given enoxacin augmented this effect. Enoxacin did not penetrate the vitreous. Enoxacin eye drops may be evaluated for their clinical usefulness in case of keratitis caused by Gram-negative bacilli.

Enoxacin is a broad-spectrum quinolone-derivative antibiotic. In a rabbit model of keratitis caused by a Pseudomonas species, enoxacin (3 mg/mL) was as effective as gentamicin sulfate (3 mg/mL) and enoxacin (10 mg/mL) in reducing viable bacterial counts in corneas after 24 hours of hourly therapy with eye drops. Bacterial counts were reduced by about 5000-fold by enoxacin treatment when compared with placebo-treated controls. Penetration studies of topical enoxacin (3 mg/mL) showed that concentrations in cornea and aqueous humor reached levels above reported minimal inhibitory concentrations when an epithelial defect was present. Further investigation of enoxacin for treatment of ocular disease is warranted.
