  • Publication number: 20240131232
    Abstract: Disclosed is an anti-adhesion agent composition which uses a high molecular weight compound having biocompatibility and an oil derived from animals, plants, and minerals so as to improve low viscosity and low strength, which are problems of existing anti-adhesion agents, and prevent adhesion between living tissues. The anti-adhesion composition according to the present disclosure performs a physical barrier function through simple mixing of a polymer material, serving as a physical barrier in its anti-adhesion effect, and a solvent, and remains in the body for a certain period of time, then decomposes, absorbs, and is excreted. The anti-adhesion composition does not interfere with the healing of the wound after surgery, and exhibits an excellent effect of convenient application to the surgical site.

  • Patent number: 9775828
    Abstract: The present invention provides a pharmaceutical composition including an ionic liquid composed of a triptan compound and saccharin. Since a triptan compound and saccharin form an ionic liquid to increase the solubility of the triptan compound in the present invention, it is possible to expect a rapid and high dissolution of the triptan compound when a pharmaceutical composition is prepared. In addition, large amounts of organic solvents and acidic solvents need not be used in order to dissolve the triptan compound.

  • Patent number: 9579261
    Abstract: Disclosed is a method for preparing a liposome formulation. In the disclosed method, a lipid fraction is dissolved in an organic solvent. The solution including a bioactive component and the lipid fraction, together with a carrier, is put in a reaction vessel, and a supercritical fluid is introduced thereto, so as to prepare particles coated with the bioactive component-lipid. The supercritical fluid is discharged by compression to obtain proliposome particles, and then the proliposome particles are hydrated by an aqueous solution including water so as to form a liposome solution. Preferably, the formulation may include one or more bioactive components. As required, the liposome formulation may be further processed by methods such as particle size reduction, removal of organic solvent, and freeze-drying. The preparation method can be easily carried out at a laboratory scale. Furthermore, the same method can be employed in liposome formulation preparation in mass production, or at a commercial scale.
