Problems solved by technology

Due to its own structural characteristics, daidzein has a relatively large shortcoming and deficiency, that is, its water solubility is poor, and it cannot be dissolved in water, which results in poor dissolution of oral preparations, resulting in low bioavailability. At the same time, injection administration cannot be administered, which limits the route of administration and dosage form, and greatly affects the clinical curative effect and clinical application range.

Embodiment 1

[0039] Example 1 Preparation of daidzein tablets

[0040]

[0041] The preparation process is as follows:

[0042] (1) Take daidzein, 35% arginine, and 20% disintegrating agent according to the prescription, mix well and make soft material with ethanol solution of 30% binder in the prescription amount, sieve with 20 meshes to make wet granules, 60 Dry at ℃ for 2h;

[0043] (2) Take the remaining arginine, the prescribed amount of diluent and 15% disintegrant, mix and add the ethanol solution of the remaining binder to make a soft material, sift through a 20-mesh sieve to make wet granules, and dry at 60°C for 2 hours;

[0044] (3) Mix the granules obtained in step 1 and step 2, add the remaining disintegrant and the prescribed amount of lubricant at the same time, mix well and press into tablets, the specification is 50mg / tablet.

Abstract

A provided daidzein-containing tablet composition comprises daidzein and arginine with the weight ratio of 1:2.5-4. The tablet composition comprises, in parts by weight, 16 parts of daidzein, 40-64 parts of arginine, 5-7 parts of a disintegrating agent, 14-38 parts of a diluent, 0.2-1.0 parts of a lubricant and 0.9-1.6 parts of an adhesive. By employing the above technical scheme, the water-soluble daidzein-containing tablet composition containing daidzein and arginine with the weight ratio of 1:2.5-4 is provided. The invention further provides a specific prescription and a preparation method. An added weak base enables daidzein to relatively well form a relatively stable easily-soluble salt, and thus improvement of dissolution rate is facilitated, and absorption by human body is facilitated. The technology is simple and the prescription quality is reliable, and batch production of the daidzein tablet can be realized.
