2. Description of the Related Art With the aging of society in recent years, the number of elderly people with decreased physiological functions and elderly people suffering from senile dementia is increasing. Such elderly people often have a decreased food intake function such as chewing or swallowing, or have a disorder in the food intake function, and when oral administration is performed with a solid pharmaceutical preparation such as tablets. , It was difficult to swallow the solid pharmaceutical preparation. Also, for patients with dysphagia and children,
If the size of the solid pharmaceutical preparation is large, there is a problem that it is difficult to take.

Therefore, JP-A-9-187233 and JP-A-9-194346 disclose oral pharmaceutical preparations which are easy to take even for the elderly and patients with dysphagia. In the above-mentioned publication, based on the report that a liquid preparation having high viscosity is preferred as a dosage form of an oral pharmaceutical preparation that can be easily taken by the elderly and patients with dysphagia, the dosage form of the oral pharmaceutical preparation is a jelly form. .
