L'invention fournit un procédé de fabrication de composition pour préparation pharmaceutique et un procédé de fabrication de préparation pharmaceutique selon lesquels la dégradation de médicament lors de la fabrication est inhibée, et une préparation pharmaceutique dotée d'excellentes propriétés de granulation et d'une dureté élevée, peut être facilement obtenue.　Le procédé de fabrication de composition pour préparation pharmaceutique de l'invention comporte une étape (1) au cours de laquelle un mélange contenant un principe actif et un agent de liaison, est malaxé à l'intérieur d'un cylindre selon un procédé d'extrusion à double vis, et soumis à une granulation, la température à l'intérieur dudit cylindre étant inférieure ou égale à １３０℃, et la masse moléculaire moyenne en poids dudit agent de liaison étant inférieure ou égale à １００００００ｇ／ｍｏｌe. Ledit mélange contient 80% en masse ou plus d'un principe actif pour l'ensemble de la masse dudit principe actif et dudit agent de liaison.
