Product properties


Danofloxacin 18%

Each ml contains 180 mg of danofloxacin as the mesylate salt.

Mechanism of Action:

Danofloxacin mesylate is a synthetic fluoroquinolone antimicrobial agent. Danofloxacin exerts its activity by inhibiting the bacterial DNA gyrase enzyme, thereby blocking DNA replication. Inhibition of DNA gyrase is lethal to bacteria and danofloxacin has rapid bactericidal effect. Danofloxacin 18% is active against gram negative and gram positive bacteria.

Danofloxacin 18% has been shown to be effective in the treatment of bovine respiratory disease associated with Pasteurella (Mannheimia) haemolytica and Histophilus somni and E.coli in calves diarrhea and bovine mastitis.

Indications of use
