| Description | Gemifloxacin, also known as factiv, belongs to the class of organic compounds known as naphthyridine carboxylic acids and derivatives. Naphthyridine carboxylic acids and derivatives are compounds containing a naphthyridine moiety, where one of the ring atoms bears a carboxylic acid group. Gemifloxacin is a drug which is used for the treatment of bacterial infection caused by susceptible strains such as s. pneumoniae, h. influenzae, h. parainfluenzae, or m. catarrhalis, s. pneumoniae (including multi-drug resistant strains [mdrsp]), m. pneumoniae, c. pneumoniae, or k. pneumoniae. Based on a literature review a significant number of articles have been published on Gemifloxacin. |
