ANTIBACTERIAL COMPOSITION FOR ORAL ADMINISTRATION

摘要

An antibacterial composition for oral administration comprising pivaloyloxymethyl-(6R,7R)-7¢(Z)-2-(2-aminothiazol-4-yl)-2-methoxyiminoacetamide!-3-¢(Z)-2- (4-methylthiazol-5-yl)-ethenyl!cephem-4-carboxylate, .beta.cyclodextrin and a pharmaceutically acceptable carrier is disclosed. The addition of .beta.-cyclodextrin remarkably improves the dispersibility of the substance ME1207 to thereby promote the absorption of the same. Thus, the absorbability of the substance ME1207 administered at a hungry state is elevated to a level comparable to that achieved by administering the same after meals.
