| titleOfInvention | Process for Preparing Drug-embeded Biodegradable Porous Polymeric Scaffold |
| abstract | The present invention relates to a porous biodegradable polymer support encapsulated with a drug having pores of various shapes and sizes, prepared using a biodegradable polyester-based polymer and an effervescent salt, and a method for preparing the same. The method for preparing a biodegradable porous polymer support in which a drug of the present invention is encapsulated includes dissolving a biodegradable polyester-based polymer and a desired drug in an organic solvent and adding a concentrated organic solvent to obtain a concentrated polymer solution; Adding a foaming salt to the electric polymer solution to obtain a gel, and removing the organic solvent from the gel thus obtained to obtain a dried gel slurry; And immersing the electric gel slurry in an acidic aqueous solution to foam the salt at room temperature, and washing to prepare a porous polymer support. When implanting the polymer support of the present invention in vivo, the drug encapsulated in the support is released slowly over a long period of time, and the drug is controlled according to the surface area of the polymer support according to the amount of drug encapsulated, the composition of the polymer and the size and mixing amount of the effervescent salt. Since the release rate can be controlled, it can be widely used for long-term medication. |
