The present invention relates to tablets that dissolve rapidly in gastric juices. Sucrose fatty acid ester is a highly safe nonionic surfactant and is used in the fields of food, medicine, and cosmetics. However, conventional sucrose fatty acid esters have low
It was thought that in the PH range, it aggregates and exhibits no dispersing or solubilizing power. For this reason, there have been no examples of adding sucrose fatty acid esters to tablets in order to quickly dissolve in gastric fluid and improve drug efficacy. As a result of intensive research on the above points, the present inventors found that monoesters of sucrose fatty acid esters have low
It was found that because it does not cause aggregation even in the pH range, it is possible to quickly dissolve the medicinal ingredients in gastric fluid even when added to tablets. That is, the present invention provides a tablet that rapidly dissolves in gastric fluid and is characterized by containing a sucrose fatty acid ester containing 90% or more of monoester. The constituent fatty acids of the sucrose fatty acid ester used in the present invention include, but are not limited to, octanoic acid, lauric acid, stearic acid, and oleic acid. However, if the carbon chain length of the constituent fatty acids is extremely short, the solubilizing power will be weak, and if it is long, the solubility in water will be poor.
22 is appropriate. Further, the amount of sucrose fatty acid ester used is not particularly limited, but in practice, it is preferably 50% or less by weight in the formulation. The above-mentioned monoester of sucrose fatty acid ester does not cause aggregation even in the low pH range, and has an excellent ability to solubilize water-insoluble components. The tablet according to the invention disintegrates in the first pharmacopoeia liquid;
Medicinal ingredients dissolve quickly. Tablets to which sucrose fatty acid esters containing a high degree of substitution of diester or higher cause aggregation in the first pharmacopoeial liquid and are ineffective. Next, typical examples of the present invention will be shown. (Department,

Do the lock. The obtained tablets were tested in accordance with Dissolution Test Method 1 of the Japanese Pharmacopoeia 10th Revised General Test Methods using Pharmacopoeia 1 Liquid. The dissolution rate was determined by measuring the absorbance of the filtrate. The composition of the sucrose fatty acid ester used is shown in Table 1, and the measurement results are shown in Table 1-2.

[Table] * The numbers indicate the dissolution rate and are expressed in %.
Comparative Example 1 In the formulation of Example 1, the monoester content was 50% as the sucrose fatty acid ester, and the constituent fatty acids
When tablets containing 30% C 16 and 70% C 18 were compressed in the same manner and measured under the same conditions, they became cloudy and could not be measured. Example 2 35 parts of powdered sugar 60 parts of carboxymethyl cellulose 1 part of magnesium stearate 4 parts of color (Blue No. 2) 4 parts of the basic recipe above and sucrose palmitate containing 98% monoester in the following proportions were mixed. The tablets were then compressed using a tablet press. The obtained tablets were tested in accordance with Dissolution Test Method 1 of the Japanese Pharmacopoeia 10th Revised General Test Methods using Pharmacopoeia 1 Liquid. The dissolution rate was determined by taking a test drug solution at regular intervals and measuring the absorbance of the filtrate after filtration.
