Description

General description

Chemical structure: fluoroquinolone

Application

Ofloxacin is a synthetic fluoroquinolone with broad-spectrum antibacterial activity. It is a nalidixic acid analog. It is given to patients before undergoing retinal reattachment surgery.

Biochem/physiol Actions

Ofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, which haults DNA replication and cell division. Ofloxacin has been shown to convert LytA from the inactive E-form to the active C-form. It is a chiral molecule that inhibits pneumococcal cell wall-degrading virulence factors.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.
