Premafloxacin is an 8-methoxy fluoroquinolone derivative patented by American pharmaceutical company Warner-Lambert Co. as an antibacterial agent. In preclinical studied. Premafloxacin was equivalent to ciprofloxacin, enrofloxacin, and danofloxacin in activity against the gram-negative bacilli but was much more active than the comparison antimicrobial agents (against the staphylococci, streptococci, and anaerobes. Premafloxacin acts as a topoisomerase IV inhibitor with enhanced activity against Staphylococcus aureus.
