TECHNOLOGY FOCUS - PHARMACEUTICALS - Preferred Method: The method involves dissolving dipotassium glycyrrhizinate in water and mixing nonionic surfactant with mixture. Preferred Components: The nonionic surfactant is chosen from polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene polyoxypropylene alkyl ether, sucrose fatty acid ester and polyglyceryl fatty acid ester, preferably polyoxyethylene octyldodecyl ether having polymerization degree of 10-20, polyoxyethylene stearyl ether having polymerization degree of 10-20, polyoxyethylene polyoxypropylene cetyl ether, where the polymerization degree of polyoxyethylene is 10-20 and polyoxypropylene is 4-8, polyoxyethylene hydrogenated castor oil having polymerization degree of 20-100 and sucrose laurate ester. The polyvalent metallic salt is polyvalent metal halide, polyvalent metal acetylation product or polyvalent metal gluconic acid compound. The polyvalent metal halide is chosen from calcium chloride, calcium bromide, calcium fluoride, calcium iodide, magnesium chloride, magnesium bromide, magnesium fluoride, magnesium iodide, zinc chloride, zinc bromide, zinc fluoride, zinc iodide, calcium acetate, magnesium acetate, zinc acetate, calcium gluconate, magnesium gluconate, zinc gluconate, aluminum gluconate, aluminum chloride, aluminum bromide, aluminum fluoride, aluminum iodide, vanadium chloride, vanadium acetate, vanadium bromide, vanadium fluoride and iodinated vanadium. The polyvalent metal inorganic salt is chosen from calcium carbonate, calcium phosphate, magnesium carbonate, magnesium phosphate, zinc carbonate and zinc phosphate. The alkali metal oxycarbide or alkali metal phosphorus oxide is chosen from sodium carbonate, potassium carbonate, sodium hydrogencarbonate, potassium hydrogencarbonate, sodium phosphate and potassium phosphate. ACTIVITY - Antiinflammatory. Test details are described but no results given.    MECHANISM OF ACTION - None given.    ADMINISTRATION - The composition is administered by oral or enteric route or injection. No dosage details given.    EXAMPLE - Ion exchange water (7.5 ml) was added and mixed with 0.3 g of dipotassium glycyrrhizinate and stirred till the component dissolved completely. Polyoxyethylene (60) hydrogenated castor oil (1.5 g) was added to solution and stirred for 1 hour or more. Magnesium chloride (2.5 M) (132 mu l) was added to the solution and stirred for 30 minutes or more. Sodium carbonate (1M) (66 mu l) was added to the solution and stirred for 30 minutes or more. Ion exchange water was further added to make the total volume to 10 ml. The transparent dispersion liquid containing glycyrrhetic acid-magnesium carbonate was obtained. The dispersion liquid was diluted with 10 times of ion exchange water. The nanoparticle was found to have particle size of 10.6-24.2 nu m and average particle diameter of 15.9 nu m.
