The present invention relates to a film preparation having both rapid solubility and flexibility at the same time. The film preparation is characterized by comprising: an active-ingredient-containing layer comprising an active ingredient, a water-soluble polymer selected from the group consisting of methyl cellulose, hydroxypropyl cellulose, and hydroxypropyl methyl cellulose, and a disintegrating agent; and an active-ingredient-free layer comprising methyl cellulose and/or hydroxypropyl methyl cellulose. It is further characterized in that the amount of the active ingredient is 0.1-75.0 mass % of a total mass of the film preparation and a total content of the active ingredient and the water-soluble polymer in the active-ingredient-containing layer is 15.0-95.0 mass % of a total mass of the active-ingredient-containing layer.

Film preparation with rapidly dissolving property and flexibility

A method and an apparatus are adapted to manufacture a tablet capable of quick disintegration in the oral cavity that has a sufficiently large porosity and can be disintegrated in the oral cavity in a very short period of time, typically between 3 and 5 seconds. A tablet manufactured by means of such a method and such an apparatus also constitutes part of the present invention. The method for manufacturing a tablet capable of quickly disintegration in the oral cavity comprises steps of punching a tablet out of a pharmaceutical composition containing one or more than one medicinal agents and one or more than one water-soluble saccharides under pressure between 0.20 and 0.01 t/cm,and shaping the tablet by moisturizing and drying it, while transferring it without causing it to drop, said tablet having a porosity between 20 and 40%.
