ABSTRACT:
Regarding an object of sufficient suppression of unpleasant taste in the oral cavity and quick dissolution in the gastrointestinal tract, which is generated when a drug having a strong unpleasant taste such as bitterness, astringency and the like is applied to a quickly disintegrating preparations in the oral cavity, this invention has achieved the aforementioned object for the first time by employing a constitution of coating a coat of a water-soluble polymer and a specified ratio of a pH-independent water-insoluble polymer and hydroxypropylcellulose.
