How does Vigamox Moxifloxacin work?

Moxifloxacin, an active ingredient of Vigamox is a sterile ophthalmic, 8-methoxy fluoroquinolone anti-infective for ophthalmic use. The antibacterial action of moxifloxacin is due to the inhibition of topoisomerase II (DNA gyrase) and topoisomerase IV. DNA gyrase is an enzyme that is responsible for the replication, transcription and repair of bacterial DNA. Topoisomerase IV is an enzyme that plays an essential role in partitioning the chromosomal DNA during bacterial cell division. It provides prolonged contact with the ocular surface that ensures a longer duration of action.
