Abstrakt: Moxifloxacin and gemifloxacin were tested on isolated rabbits' jejunal preparations as little is known about its effects on gastrointestinal tissues. Moxifloxacin and gemifloxacin were tested in concentrations 0.01-10μg/mL for possible effect(s) on isolated rabbits' jejunal preparations. The drugs were applied on spontaneous, on low K + (20mM)-induced contractions and on high K + (80mM)-induced contractions. Response was plotted as % of its respective controls. EC50 for Moxifloxacin and Gemifloxacin on spontaneous (without Glibenclamide) contractions are 2.83±0.5μg/mL and 1.11±0.2μg/mL, respectively. Moxifloxacin and Gemifloxacin relaxed the low K+ (20mM) -induced contractions, which were inhibited in presence of Glibenclamide (3μM). Our result indicates that the relaxant activity of Moxifloxacin and Gemifloxacin is mediated possibly through activation of ATP-sensitive potassium channels (KATP). The relaxant effect of Moxifloxacin and Gemifloxacin is predominantly mediated by activation of ATP-Sensitive potassium channels (K ATP ), which could be cause of one of relaxing mechanisms.
