  • Antofloxacin hydrochloride is a well tolerate, orally active and broad-spectrum 8-amino-fluoroquinolone with potent antibacterial activities. Antofloxacin hydrochloride shows superior antibacterial activity against gyrA mutation-positive H. pylori strains, especially in Asn87- mutated strains, compared to levofloxacin. Antofloxacin hydrochloride is a weak, reversible inhibitor of CYP1A2 for the treatment of infections caused by a diverse group of bacterial species[1][2][3].

In Vivo Antofloxacin (2.5~160 mg/kg; s.c.; 24 hours) penetration ratio ranges from 1.22 to 1.54 for the total drug concentrations and is independent of the dose levels[3].Antofloxacin increases the plasma theophylline concentration, partly by acting as a mechanism based inhibitor of CYP1A2. Antofloxacin inhibits the formation of the three metabolites of theophylline was time-, concentration- and NADPH-dependent, which is characteristic of mechanism-based inhibition[2]. Animal Model: Mice (Pharmacokinetic Analysis)[3] Dosage: 2.5~160 mg/kg Administration: S.c.; 24 hours Result: Penetration ratio ranged from 1.22 to 1.54 for the total drug concentrations and was independent of the dose levels.
