FUNCTIONAL POLYMER FILM-COATED PARTICLE HAVING HIGH DRUG CONTENT, TABLET CONTAINING SAME, AND METHODS FOR PRODUCTION THEREOF

摘要

Provided are functional drug-containing particles which can be compressed into tablets and in particular, to orally disintegrating tablets by employing any of a dry molding method, a wet molding method, or a humidifying drying method. The functional drug-containing particles comprise substantially spherical drug-containing particles essentially including drug and a binder, the functional drug-containing particles including a functional polymer film selected from the group consisting of an enteric film, a release control film, and a bitter taste masking film, an average particle diameter of said functional drug-containing particles being 400 µm or less, a particle diameter ratio D 90 /D 10 of the functional drug-containing particles with respect to particle size distribution calculated on a volumetric basis being 1.65 or more, or a coefficient of variation in particle diameters being 24% or more.
