Pharmacodynamics | Temafloxacin (marketed by Abbott Laboratories as Omniflox), is a fluoroquinolone antibiotic drug which was withdrawn from sale in the U.S. shortly after its approval in 1992 because of serious adverse reactions resulting in three deaths. Flouroquinolones such as lomefloxacin possess excellent activity against gram-negative aerobic bacteria such as E.coli and Neisseria gonorrhoea as well as gram-positive bacteria including S. pneumoniae and Staphylococcus aureus. They also posses effective activity against shigella, salmonella, campylobacter, gonococcal organisms, and multi drug resistant pseudomonas and enterobacter. |
Mechanism of action | The bactericidal action of temafloxacin results from interference with the activity of the bacterial enzymes DNA gyrase and topoisomerase IV, which are needed for the transcription and replication of bacterial DNA. DNA gyrase appears to be the primary quinolone target for gram-negative bacteria. Topoisomerase IV appears to be the preferential target in gram-positive organisms. Interference with these two topoisomerases results in strand breakage of the bacterial chromosome, supercoiling, and resealing. As a result DNA replication and transcription is inhibited. |
Absorption | Studies in healthy volunteers indicate that the average bioavailability of temafloxacin exceeds 90%, with little intersubject variability. |
