Abstract:
The present invention relates to extended release microparticles comprising a drug, and a preparation method therefor, and when the extended release microparticles comprising a drug are administered in order to replace conventional drugs that should be administered daily or monthly, the drug administration effect can be continuously maintained for one week to three months. In addition, the drug administration effect is maintained for a long time and, simultaneously, particles are prepared so as to have the average diameter of a fixed micro-size, and thus an effective drug concentration can be constantly maintained by controlling the release of the drug from the microparticles, and a foreign body sensation and pain can be reduced during drug administration since microparticles having a uniform size are included during application as an injectable drug.
