Ofloxacin is an antibacterial agent used for the treatment of bacterial infections in many parts of the body, including the respiratory tract, kidney, skin, soft tissue, and urinary tract.
Ofloxacin inhibits DNA gyrase (topoisomerase II) and topoisomerase IV. These proteins prevent supercoiling in bacterial DNA. The inhibition of DNA gyrase (topoisomerase II) and topoisomerase IV causes supercoiling of the bacterial DNA. This prevents DNA replication.
