Technical Field

[0001] The present invention relates to the technical field of production and processing of ethylamine, pyrazine, and rifampicin tobacco tablets, and in particular to a high-efficiency ethylamine, pyrazine, and rifampicin tobacco tablet and a preparation method thereof. Background Art

[0002] Tuberculosis is an infectious disease caused by the bacillus Mycobacterium tuberculosis. It usually affects the lungs, but can also affect other parts of the body. According to the WHO, approximately one-third of the world's population is infected with the disease. The development of drug-resistant tuberculosis is a major public health concern because it threatens the future of tuberculosis control. Drug resistance in tuberculosis patients is mainly due to poor patient compliance with treatment. When using a single drug combination, patients need to take 6-8 tablets once a day on an empty stomach. Failure to fully comply with treatment leads to the development of multidrug-resistant strains of tuberculosis. Summary of the Invention

[0003] To this end, the present invention provides a method for preparing high-efficiency ethamidine pyrazine and rifampicin tobacco tablets, the steps comprising: (1) Weighing the sieved isoniazid, pyrazinamide, and ethambutol hydrochloride according to the formula amount, then mixing the isoniazid, pyrazinamide, microcrystalline cellulose, and pregelatinized starch, stirring evenly to obtain isoniazid particles; mixing the ethambutol hydrochloride, microcrystalline cellulose, and pregelatinized starch, stirring evenly to obtain ethambutol particles; (2) preparing a mixed aqueous solution of povidone K30 and sodium lauryl sulfate to prepare an aqueous solution of povidone K30; spraying the aqueous solution of povidone K30 into the iso-yan granules under stirring to obtain an iso-yan soft material, and then granulating, drying, and sizing to obtain iso-yan dry granules; spraying the mixed aqueous solution of povidone K30 and sodium lauryl sulfate into the ethylamine granules under stirring to obtain an ethylamine soft material, and then granulating, drying, and sizing to obtain ethylamine dry granules; (3) The ethylamine dry particles are mixed with talc and rifampicin, and stirred evenly to obtain a first mixture.

The preparation method of the rifampicin inclusion complex is as follows: Step 1: Mix olive leaf dry powder and kelp dry powder to form a mixed powder, add the mixed powder to a cellulase hydrolyzate, adjust the pH to 5-5.5 with hydrochloric acid, then heat in a water bath to 55-60° C., extract at a constant temperature for more than 5 hours, then inactivate the enzyme, separate the solid and liquid, concentrate the liquid phase under reduced pressure, and freeze-dry to obtain an olive leaf-kelp hydrolyzate; Step 2: preparing an aqueous solution of acetic acid, adding soybeans to the aqueous solution of acetic acid, soaking at room temperature for more than 5 hours, then filtering, washing the soybeans with deionized water for more than 3 times, adding deionized water, and beating with a beater to make soy milk, filtering the soy milk with nylon cloth to remove bean dregs, adding neutral protease to the filtrate, heating to 50±3° C. in a water bath after adding the enzyme, keeping the temperature for enzymatic hydrolysis for more than 2 hours, then inactivating the enzyme, centrifuging, concentrating the supernatant under reduced pressure, and freeze-drying to obtain the soybean hydrolyzate; Step 3: Mix rifampicin, the olive leaf-kelp hydrolysate, hydroxypropyl-β-cyclodextrin and soybean hydrolysate, stir the mixture for more than 10 minutes, and then grind it for more than 30 minutes to obtain the rifampicin inclusion complex.

7. The method for preparing a high-efficiency ethamidine pyrazine and rifampicin tobacco tablet according to claim 6, characterized in that: In the step 1, the mass ratio of the olive leaf powder and the kelp powder is olive leaf powder: kelp powder = 10:2-10; the concentration of cellulase in the cellulase hydrolysate is 80-100 mg / 100 mL, the solvent is water, and the amount ratio of the mixed powder added to the cellulase hydrolysate is mixed powder: cellulase hydrolysate = 1 g: 50-80 mL; the mass percentage of the solute in the hydrochloric acid is 10%.

8. The method for preparing a high-efficiency ethamidine pyrazine and rifampicin tobacco tablet according to claim 6, characterized in that: In step 2, the mass percentage of the solute in the aqueous solution of acetic acid is 5% to 6%, and the solvent is water; the mass ratio of the soybeans added to the aqueous solution of acetic acid is soybeans: acetic acid aqueous solution = 1:5 to 10; the washed soybeans are added to deionized water at a mass ratio of soybeans: water = 1:8 to 10 for pulping; the volume ratio of the added mass of neutral protease to the filtrate is neutral protease: filtrate = 3 to 4 g: 100 mL.

9. The method for preparing a high-efficiency ethamidine pyrazine and rifampicin tobacco tablet according to claim 6, characterized in that: In the step three, the mass ratio of rifampicin, the olive leaf-kelp hydrolysate, hydroxypropyl-β-cyclodextrin and soybean hydrolysate is rifampicin: olive leaf-kelp hydrolysate: hydroxypropyl-β-cyclodextrin: soybean hydrolysate = 10:1~2:16~18:2~6.
