PROBLEM TO BE SOLVED: To provide a mask which masks a taste by coating the surface of the drug with a small coating amount and, after a certain period of time, elutes the drug. SOLUTION: The taste-masked drug whose surface is coated with an aqueous coating solution containing substantially solid spherical particles having a diameter of 1 μm or less containing ethyl cellulose as a main component, a plasticizer and an elution controlling agent. [Effect] With a small amount of coating, the elution of the drug is ensured, and the change in the elution due to the (compression) treatment is small. |
