Trovafloxacin (sold as Trovan by Pfizer and Turvel by Laboratorios Almirall) is a broad spectrum antibiotic that inhibits the uncoiling of supercoiled DNA in various bacteria by blocking the activity of DNA gyrase and topoisomerase IV.[1] It was withdrawn from the market due to the risk of hepatotoxicity. It had better gram-positive bacterial coverage and less gram-negative coverage than the previous fluoroquinolones.
