GATIFLOXACIN vs ZAGAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Gatifloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination.
Sparfloxacin, a fluoroquinolone antibiotic, inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, thereby blocking DNA replication and transcription.
