Ciprofloxacin is a synthetic broad-spectrum antimicrobial agent for intravenous administration. The bactericidal action of Ciprofloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.
