The invention more specifically relates to a polymer fine particle produced by the production method and a method of polymer particles the initial drug release is reduced includes the step of the manufacturing method of the polymer fine particles, treated in alcoholic aqueous solution to the polymer particles relates to the initial release (initial burst) of the method is reduced drug encapsulated polymer particles produced, the polymer fine particle and a drug delivery composition containing the same prepared by the above method. The present invention provides a new method for producing polymer particles with reduced initial release rate. The process of the present invention may be useful for the purpose of providing a new drug in the dosage form to prevent a number of side effects caused by excessive release of the drug.
