  • Title: [Influence of food intake on the bioavailability of ponsinomycin administered in a syrup form].

    Abstract:
    Ponsinomycin is a new macrolide. Following oral administration, ponsinomycin is totally metabolized, even before reaching blood circulation. Metabolite Mb12 is the first compound on the main metabolic route, which can be assayed. The influence of food on ponsinomycin bioavailability has therefore been estimated from measurements of Mb12 plasma levels. Twelve young healthy volunteers received 800 mg of ponsinomycin as a syrup on two separate occasions, 2 hours before and during a standard meal. The Mb12 metabolite was assayed in plasma by High Pressure Liquid Chromatography (HPLC). Plasma peak concentrations and areas under curves were not significantly different but time to peak was significantly shorter when ponsinomycin was administered during meal. The results suggest that ponsinomycin absorption is faster when administered with food but quantitatively unchanged.
