In general, pharmaceuticals for treating liver diseases, whether acute or chronic, require continuous administration of the agents for a relatively long period of time. Glycyrrhizin oral agents have been developed and used to reduce the frequency of patient visits to hospitals and to reduce the burden of hospital visits.However, in the case of oral administration of glycyrrhizin, which is expected to have a systemic effect on the market, it is decomposed by gastric acid or in the liver.

Has been done. However, from the standpoint of the patient, an oral preparation that is easier to use than a suppository is desired if the effect is certain. As an oral preparation having improved transferability into blood, there is a report on a preparation containing a fatty acid glyceride and an enteric coating (Japanese Patent Laid-Open No. 3-255037).
However, it cannot be considered that this preparation shows a sufficient blood transfer property as compared with the blood concentration of an injection for which the effect is confirmed.

[Means and Actions for Solving the Problems] Therefore, as a result of diligent studies on the method of improving the transmissibility of glycyrrhizin and its salts into blood upon oral administration, the present inventors have found that glycyrrhizin and its salts A fat emulsion or complex lipid mixture, or a dry powder thereof, containing at least one of medium chain fatty acid and its salts and its glyceride or nonionic surfactant as an absorption promoter, and molded into a formulation by a conventional method, In addition, the formulation is coated with an enteric coating.
That is, it was found that when the release of the main drug and the absorption enhancer from the preparation is carried out in the upper small intestine, it exhibits extremely excellent absorbability as compared with the conventional oral preparation.

Test Example 4 20 mg / Kg of GLH 2 (glycyrrhizinic acid) was orally administered to rats that had been fasted for 24 hours, and Examples 5 and 6 were orally administered.
The abdomen was sutured, blood was collected from the jugular vein over time, and plasma was obtained by a conventional method. The glycyrrhizic acid concentration in this plasma was measured by high performance liquid chromatography to determine AUC 0-8 . Then, the utilization rate was calculated by comparison with the injection.
