Embodiment 1

[0066] Add 75% capecitabine to a 120-mesh sieve, microcrystalline cellulose 10% (w / w), and croscarmellose sodium 15% (w / w) into a three-dimensional motion mixer and mix thoroughly Uniformly; put the uniformly mixed material into a high-efficiency wet granulator, and set aside; add 5% polyvinylpyrrolidone K30 soft material, pass through a 20-mesh sieve, dry at 50°C, dry for 6 hours, granulate, and mix Uniform, ready to be pressed into tablets.

Embodiment 2

[0068] Add 80% capecitabine to a 120-mesh sieve, microcrystalline cellulose 7.5% (w / w), and croscarmellose sodium 7.5% (w / w) into a three-dimensional motion mixer and mix thoroughly Uniformly; put the uniformly mixed material into a high-efficiency wet granulator, and set aside; add 5% polyvinylpyrrolidone K30 soft material, pass through a 20-mesh sieve, dry at 50°C, dry for 6 hours, granulate, and mix Uniform, ready to be pressed into tablets.

Embodiment 3

[0070] Add capecitabine 75%, microcrystalline cellulose 15% (w / w), and croscarmellose sodium 7.5% (w / w) into a three-dimensional motion mixer, and mix well; Put the material into a high-efficiency wet granulator, and set it aside; add 2.5% polyvinylpyrrolidone K30 soft material, pass through a 20-mesh sieve, dry, granulate, mix evenly, and tablet.

Abstract

The invention discloses a capacitabine dispersible tablet and a preparation method thereof. The formula of the dispersible tablet is as follows: the proportion of a main drug of capacitabine ranges from 70%-80%; the proportion of an adhesive of polyvinylpyrrolidone K30 ranges from 3%-7%; the proportion of a disintegrating agent of cross-linked sodium carboxymethyl cellulose ranges from 3%-7%; and the proportion of a filling agent of microcrystalline cellulose ranges from 10%-20%.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a safe and stable capecitabine dispersible tablet and a preparation method thereof. Background technique [0002] Capecitabine (English name Capecitabine) is the first oral fluoropyrimidine carbamate antineoplastic drug, and its chemical name is 5′-deoxy-5-fluoro-N[(pentyloxy)carbonyl]-cell ( pyrimidine nucleosides. Chemical Structure: [0003] [0004] Capecitabine is suitable for single-drug adjuvant therapy for colon cancer patients with Dukes' C stage, after radical resection of the primary tumor, who are suitable for fluoropyrimidine therapy alone. The disease-free survival (DFS) of its treatment is not inferior to that of 5-fluorouracil and leucovorin (5-FU / LV). Neither capecitabine alone nor in combination with other drugs can prolong overall survival (OS), but experimental data have shown that capecitabine in combination chemotherapy can improve disease-fr...
