Disclosed is a pharmaceutical composition for release control comprising a plurality of particles for release control. The plurality of particles for release control comprise a core material containing methylphenidate and a polymer coating layer for release control formed on the core material. The plurality of particles for release control are divided into two or more groups based on the average thickness of the polymer coating layer for release control. The particle groups are identical in terms of the composition of the polymer in the polymer coating layer, but are different in terms of the average thickness of the coated layer. The pharmaceutical composition for release control according to the present invention may control the release pattern of methylphenidate contained in the core material as desired, and can be used as an oral formulation in a variety of forms such as orally disintegrating tablets, etc.
