No.: 11/102,760 comprising a water-insoluble and/or water-low Soluble Sub stance, a medicament, and an aqueous medium, and having (22) Filed: Apr. 11, 2005 an osmotic pressure of less than 290 mOsm. This compo Sition is Superior over conventional pharmaceutical compo Related U.S. Application Data Sitions for application to the mucosa, due to efficient and high permeability to the blood at the mucosa. The present (63) Continuation of application No. 10/201,303, filed on invention further provides a pharmaceutical composition for Jul. 24, 2002, which is a continuation of application application to the mucosa comprising a hemostatic agent and No. 09/446,276, filed on Dec. 21, 1999, filed as 371 a medicament. This composition is Superior over conven of international application No. PCT/JP99/02126, tional pharmaceutical compositions for application to the filed on Sep. 28, 1999. mucosa, due to permeability and retentivity at the mucosa.

The present invention relates to a pharmaceutical enabling quick and efficient absorption of the a growth composition for application to the mucosa to be used in drug hormone-releasing factor through the nasal mucosa to the therapy comprising a water-insoluble and/or water-low blood circulation. Furthermore, Ohwaki et al. (Japanese Soluble Substance, a medicament, and an aqueous medium, Unexamined Patent Publication (Kokai) No. 60 (1985)- and having an OSmotic pressure of less than 290 mOsm. 123426) provides a method of applying to the nasal cavity More specifically, the present invention relates to a phar a Solution of Secretin having an OSmotic preSSure ratio of 1 maceutical composition for application to the mucosa com to 5 (an osmotic pressure of 290-1450 mOsm) and a pH of prising a water-insoluble and/or water-low Soluble Sub 2 to 5 as a method for enabling quick absorption of Secretin stance, a medicament, and an aqueous medium, and having through the nasal mucosa to blood circulation. Furthermore, an osmotic pressure of less than 290 mOsm, that is Superior Awatsu et al. (Pharm. Res. Vol. 10, No. 9, 1372-1377, 1993) to conventional pharmaceutical compositions for application provides a method of applying to the nasal mucosa a to the mucosa, due to efficient and high permeability to the pharmaceutical Solution to which polyoxyethylene 9-lau blood at the mucosa. rylether was added as an absorption enhancer as a method 0002 The present invention also relates to a pharmaceu for enabling efficient absorption of a granulocyte colony tical composition for application to the mucosa comprising Stimulating factor through the nasal mucosa to blood circu a hemostatic agent and a medicament.

However, when these pharmaceutical preparations for application to the mucosa in which a medicament has are given to the mucosa, liquid-dripping can occur, or the been mixed with a hemostatic agent and that is Superior over pharmaceutical preparations are quickly excreted to the conventional pharmaceutical compositions for application to outside of the mucus tissue due to a mucociliary clearance the mucosa due to high permeability and retention at the function etc. before being adequately transported or perme COS. ated to the mucosa tissue. Because of this, the transport of an adequate amount of drug into the blood cannot be effected BACKGROUND ART when systemic administration through transport to the blood 0003) Application to the mucosa as a method of drug circulation is attempted. Furthermore, the method of using therapy has been recognized as a useful means of medication an absorption enhancer is yet to be realized because the for Such reasons as (1) it permits direct application to the absorption enhancer has the problem of irritating the nasal affected area for diseases of local areas Such as nasal mucosa. On the other hand, when local administration is mucosa, oral mucosa, and vaginal mucosa, (2) its immediate attempted through retention of the drug in the mucosa tissue, effects for Systemic diseases can be expected as in the case an adequate amount of the drug cannot be retained at the of a nasal Spray to the nasal mucosa and a Suppository to the tissue.
