Abstract:
The present invention provides a composition containing an enzyme and deoxycholate or salts thereof and a method for stabilizing an enzyme, comprising the step of preparing the composition by adding deoxycholate or the salts thereof to the enzyme. According to the enzyme composition and the method for stabilizing the enzyme, a period of maintaining the activity of a lyophilization reagent and an injection solution reconstituted by the lyophilization reagent in a refrigerator and at room temperature extended. Therefore, the liquid formulation enables long-term maintenance with stability when being divided and used.

Abstract:
PURPOSE: A controlled release agent containing cilostazol and a method for producing the same are provided to maintain the effective drug concentration in blood and improve medicine compliance. CONSTITUTION: A controlled release agent of cilostazol comprise a solid dispersion granule containing 10-80 weight% of cilostazol and 0.1-50 weight% of solubilizing agent and 5-80 weight% of hydrogel forming material. A method for producing the controlled release agent of cilostazol comprises: a step of mixing cilostazol or its pharmaceutically acceptable salt and solubilizing agent to granulate; and a step of mixing the drug granule with hydrogel than granulating.
Abstract:
A sustained-release porous microparticle for pulmonary delivery of a charged protein drug is provided to rapidly deliver the charged protein drug to epidermal cells in deep part of the lung without macrophage damage, thereby maintaining stability of the protein drug and continuously releasing the protein drug for a long period of time. A sustained-release porous microparticle for pulmonary delivery of a charged protein drug is prepared by (1) solubilizing cyclodextrin derivatives, ionic polysaccharides and a charged protein drug in water to prepare an inner water phase, (2) adding biodegradable polymer into organic solvent to prepare an organic phase, (3) mixing the inner water phase of step (1) with the organic phase of step (2) to prepare a first emulsion, and (4) spraying the first emulsion to an outer aqueous continuous phase containing an aqueous coating material, and has an average particle diameter of 5-100 mum.
