Pharmacology
Moxifloxacin is a synthetic broad spectrum, flouroquinolone derivative antibacterial agent. Moxifloxacin has in vitro activity against a wide range of Gram-positive and Gram-negative microorganisms. The bactericidal action of Moxifloxacin results from inhibition of the topoisomerase II (DNA gyrase) and topoisomerase IV required for bacterial DNA replication, transcription, repair and recombination.

The duration of therapy depends on the type of infection as described bellow- In Acute Bacterial Sinusitis: Moxifloxacin 400 mg is given once daily for 10 days.
