Namely, a liquid matrix which is a liquidnassistant for facilitating swallowing medicine characterizednin comprising a water-soluble polymer gelling under acidicnconditions, and the breaking stress of the gel is about 3.00n×10 3 N/m 2 or more. Liquid oral preparations have favorablenslow release properties even though being a liquid. |
