Abstract
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.
