Abstract
A pharmaceutical composition comprising a physiologically active polypeptide, an absorption promoting agent consisting of a combination of an organic acid and a fatty acid sucrose ester in admixture with a pharmaceutically acceptable carrier or diluent, which is suitable for oral administration and for application to the oral cavity, by which the polypeptide can sufficiently be absorbed through the intestinal tract or the mucous membrane in the oral cavity and exhibit the physiological activities without being suffered from enzymolysis.
Claims5
