Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/1662889
Curator's Comment: description was created based on several sources, including: https://www.wikigenes.org/e/chem/e/60021.html http://www.wikidoc.org/index.php/Temafloxacin https://www.ncbi.nlm.nih.gov/pubmed/8086558

Temafloxacin (marketed by Abbott Laboratories as Omniflox) is almost completely absorbed from the gastrointestinal tract, with an absolute bioavailability of approximately 93% and is not greatly affected by food. The time to reach peak concentrations ranges between 2 and 3 hours. In addition to the broad spectrum of activity all fluoroquinolones have against gram-negative pathogens, temafloxacin has improved antimicrobial activity against gram-positive aerobic cocci, intracellular microorganisms, and anaerobes. The bactericidal action of temafloxacin results from interference with the activity of the bacterial enzymes DNA gyrase. Omniflox was approved to treat lower respiratory tract infections, genital and urinary infections like prostatitis, and skin infections in the U.S. by the Food and Drug Administration in January 1992. Severe adverse reactions, including allergic reactions and hemolytic anemia, developed in about fifty patients during the first four months of its use, leading to three patient deaths. Abbott withdrew the drug from sale in June 1992.
