PROBLEM TO BE SOLVED: To provide an intraoral patch having the form of glycyrrhetic acid being watersoluble at an intraoral temperature.SOLUTION: It is preferable to use an aqueous salt (SGE) of a glycyrrhizin licorice extract to obtain a high-volume uptake in a local tissue, or to obtain a high-efficacy as compared with a drug amount used (to minimize a risk of side effects). The SGE contains a group of chemical salts of glycyrrhetic acid, including potassium salt of the glycyrrhetic acid and alkalimetal salt of the glycyrrhetic acid. |
