Ofloxacin is used to treat certain infections including pneumonia, and infections of the skin, bladder, reproductive organs, and prostate (a male reproductive gland).
Ofloxacin is a quinolone antimicrobial agent. The mechanism of action of ofloxacin and other fluoroquinolone antimicrobials involves inhibition of bacterial topoisomerase IV and DNA gyrase (both of which are type II topoisomerases), enzymes required for DNA replication, transcription, repair and recombination.
