Protection of Hamsters from Mortality by Reducing Fecal Moxifloxacin Concentration with DAV131A in a Model of Moxifloxacin-Induced Clostridium difficile Colitis.

ABSTRACT: Lowering the gut exposure to antibiotics during treatments can prevent microbiota disruption. We evaluated the effects of an activated charcoal-based adsorbent, DAV131A, on the fecal free moxifloxacin concentration and mortality in a hamster model of moxifloxacin-induced Clostridium difficile infection. A total of 215 hamsters receiving moxifloxacin subcutaneously (day 1 [D1] to D5) were orally infected at D3 with C. difficile spores. They received various doses (0 to 1,800 mg/kg of body weight/day) and schedules (twice a day [BID] or three times a day [TID]) of DAV131A (D1 to D8). Moxifloxacin concentrations and C. difficile counts were determined at D3, and mortality was determined at D12 We compared mortality rates, moxifloxacin concentrations, and C. difficile counts according to DAV13
