Orbifloxacin is a fluoroquinolone antimicrobial agent similar to enrofloxacin and exhibits bactericidal activity against numerous Gram-negative and Gram-positive bacteria.

In canine practice, orbifloxacin is indicated for the treatment of various infections, including urinary, skin, and otitis infections. It is specifically active against E. coli and Pseudomonas aeruginosa[1].

It does not appear as efficacious as enrofloxacin, ciprofloxacin or marbofloxacin against Staphylococcus pseudintermedius[2].

Recommended dose rate in dogs is 2.5 - 7.5 mg/kg given orally every 24 hours.
