Embodiment 1

[0048] In this embodiment, the formulation of the pharmaceutical composition is as follows:

[0049]

[0050] The fluidized bed one-step granulation process is adopted. Part of the starch is added internally, and part of it is made into starch slurry and mixed with hypromellose solution as a spray liquid. The steps are as follows:

[0051] (1) 50g starch is dispersed with purified water to make starch slurry, the mass percent concentration of the starch slurry is 13%, and hypromellose and purified water are weighed to form hypromellose Solution (concentration is 10%), starch slurry and hypromellose solution are mixed to obtain spray liquid;

[0052] (2) After mixing the remaining starch with vorinostat and low-substituted hypromellose, place it in a fluidized bed, preheat the material at 40-50°C, and spray the spray liquid obtained in step (1), Granulation and drying are carried out simultaneously, and sieved to make dry granules;

[0053] (3) Add magnesium stearate to th...

Abstract

The invention provides a pharmaceutical composition for treating tumor and a preparation method and application thereof. The pharmaceutical composition comprises vorinostat and pharmaceutically acceptable adjuvant materials, wherein the pharmaceutically acceptable adjuvant materials comprise a filling agent, a binder, a disintegrating agent and a lubricating agent. The pharmaceutical composition and the preparation method thereof have the advantages that the pharmaceutically acceptable adjuvant materials are used to coordinate with the vorinostat so as to achieve even and stable particle granularity, and a fast dissolution feature is achieved to increase the antitumor effect of the vorinostat; during preparation, a fluidized bed top spray granulation method is used to allow the particle granularity to be even and stable, especially part of the filling agent is specifically used to prepare filling agent slurry which is mixed with a binder solution to serve as spraying liquid, the other part of the filling agent is mixed with other materials in a dry powder form to serve as fluidized bed materials, the particle granularity is well controlled through the spraying using the spraying liquid, particle properties are improved, stability is increased, preparation dissolution degree is increased, the preparation process is simple and controllable, and staff can be well protected.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation, and relates to a medicine composition for treating tumors, a preparation method and application thereof. Background technique [0002] Tumor is second only to cardiovascular and cerebrovascular diseases and seriously threatens the second killer of human life and health. At present, the incidence of malignant tumors in my country is increasing at a rate of 2.5% per year, and the mortality rate is increasing by about 1.3% per year. Chemotherapy has become one of the important means of comprehensive treatment of malignant tumors. Vorinostat (SAHA), chemical name "N-hydroxy-N'-phenylsuberamide", is a histone deacetylase inhibitor, which can inhibit the activity of histone deacetylase (HDAC) activity, and then promote the acetylation of histones, and ultimately inhibit the growth of cancer cells, induce cancer cell differentiation and apoptosis. Treatment of cutaneous T-cell lymphoma (C...
