  • Stable pharmaceutical composition and method for its production
    Patent number: 5298246
    Abstract: The present invention is directed to a stable pharmaceutical composition wherein the absorbability of a lipophilic drug which is insoluble or practically insoluble in water or another drug such as a bioactive peptide in oral administration has been improved to such extent that a high level of blood concentration can be retained, and to a method for producing such a stable pharmaceutical composition. The pharmaceutical composition of the present invention offers improvements in the absorbability, for example, a high level of blood concentration can be retained for a long time in oral administration because it is highly resistant to lipase. Also, the pharmaceutical composition is highly safe because the emulsifier used is derived from mammalian milk.
