Gatifloxacin is an antibiotic of the fourth-generation fluoroquinolone family that inhibits the bacterial enzymes DNA gyrase and topoisomerase IV. Gatifloxacin is a fluoroquinolone antibiotic, with potent activity against Gram-negative and Gram-positive bacteria. Bristol-Myers Squibb introduced Gatifloxacin in 1999 under the proprietary name Tequin for the treatment of respiratory tract infections. Allergan produces it in eye-drop formulation under the names Zymar and Zymaxid. In many countries, gatifloxacin is also available as tablets and in various aqueous solutions for intravenous therapy.
