Sitafloxacin is a quinolone broad-spectrum antibacterial drug, which was successfully developed by Japan Daiichi Pharmaceutical Sankyo Co., Ltd. It has good pharmacokinetic properties due to its molecular structure containing a cis-fluorocyclopropylamine group. It can reduce adverse reactions, and its in vitro antibacterial activity is significantly enhanced compared with most similar drugs. Oral tablets and fine granules were first launched in Japan in June 2008 for the treatment of severe and refractory infectious diseases. The injection form is undergoing phase III clinical trials in Japan by Japan Daiichi Pharmaceutical Company for the treatment of bacterial infections.
