Summary for Patent: 6,939,559

Title:	Pharmaceutical composition for application to mucosa
Abstract:	The present invention provides a pharmaceutical composition for application to the mucosa to be used in drug therapy comprising a water-insoluble and/or water-low soluble substance, a medicament, and an aqueous medium, and having an osmotic pressure of less than 290 mOsm. This composition is superior over conventional pharmaceutical compositions for application to the mucosa, due to efficient and high permeability to the blood at the mucosa. The present invention further provides a pharmaceutical composition for application to the mucosa comprising a hemostatic agent and a medicament. This composition is superior over conventional pharmaceutical compositions for application to the mucosa, due to permeability and retentivity at the mucosa.
