Easily dosable solid preparation

摘要

The object is to provide a preparation for oral administration having improved dosability, and/or a coating composition to be used in an easily dosable preparation, the coating composition not affecting elution properties. The object can be achieved by using a coating composition comprising a first thickener selected from the group consisting of a carboxyvinyl polymer and sodium alginate, a polyvalent metal compound, and a second thickener comprising at least one member selected from the group consisting of xanthan gum, guar gum and sodium alginate (provided that when the first thickener is sodium alginate, the second thickener is not sodium alginate), or a coating composition which comprises hydroxypropylmethylcellulose as a thickener and contains a sugar or sugar alcohol having a solubility at 20
