Problems solved by technology

[0009] In addition, due to the small size of the solid pharmaceutical composition of fingolimod and its pharmaceutically acceptable salts (the size of the original preparation is 0.5 mg), and the large amount of excipients, it is very difficult to control the uniformity of the content, which may cause each Inconsistent intake affects curative effect and increases adverse reactions

Embodiment 1

[0069] Pharmaceutical compositions using only microcrystalline cellulose as excipients:

[0070]

[0071] Preparation method: Pass the micronized fingolimod hydrochloride through a 200-mesh sieve. The prescribed amount of fingolimod hydrochloride and microcrystalline cellulose are mixed uniformly in equal amounts to obtain the pharmaceutical composition of the present invention. After heating at 60° C. for 40 hours, inspect and check the content changes of impurities and fingolimod hydrochloride. The inspection results show that the impurity content of the composition is 0.14, and the main drug content is 99.9%.

[0072] The composition is compressed into tablets or filled into capsules according to the required dosage.

Embodiment 2

[0074] Pharmaceutical compositions using only microcrystalline cellulose as excipients:

[0075]

[0076]Preparation method: Pass the micronized fingolimod hydrochloride through a 200-mesh sieve. The prescribed amount of fingolimod hydrochloride and microcrystalline cellulose are mixed uniformly in equal amounts to obtain the pharmaceutical composition of the present invention. After heating at 60° C. for 40 hours, inspect and check the content changes of impurities and fingolimod hydrochloride. The inspection results show that the impurity content of the composition is 0.13%, and the main drug content is 101.9%.

[0077] The composition is compressed into tablets or filled into capsules according to the required dosage.

Embodiment 3

[0079] Pharmaceutical compositions using only microcrystalline cellulose as excipients:

[0080]

[0081] Preparation method: Pass the micronized fingolimod hydrochloride through a 300-mesh sieve. The prescribed amount of fingolimod hydrochloride and microcrystalline cellulose are mixed uniformly in equal amounts to obtain the pharmaceutical composition of the present invention. After heating at 60° C. for 40 hours, inspect and check the content changes of impurities and fingolimod hydrochloride. The inspection results show that the impurity content of the composition is 0.15%, and the main ingredient content is 102.2%.

[0082] The composition is compressed into tablets or filled into capsules according to the required dosage.

Abstract

The invention relates to the field of chemical pharmaceutical preparations, especially to an oral solid pharmaceutical composition containing Fingolimod or its pharmaceutically acceptable salt. Specifically, the invention relates to a pharmaceutical composition containing Fingolimod or its pharmaceutically acceptable salt, microcrystalline cellulose and (or) other pharmaceutical excipients or carriers. The pharmaceutical composition provided by the invention has the characteristics of stable preservation performance, high content uniformity, and excellent dissolution performance.

Description

technical field [0001] The invention relates to the field of chemical pharmaceutical preparations, in particular to an oral solid pharmaceutical composition containing fingolimod or a pharmaceutically acceptable salt thereof. Background technique [0002] Fingolimod, chemical name 2-amino-2-(2-[4-octylphenyl]ethyl)-1,3-propanediol, molecular formula C 19 h 33 NO 2 , its structural formula is as follows: [0003] [0004] Fingolimod and its pharmaceutically acceptable salts are newly developed immunosuppressants in recent years, with a unique mechanism of action, strong immunosuppressive effect, and less toxic and side effects. The drug selectively reduces the number of lymphocytes in peripheral blood and tissues, significantly prolongs the survival of transplanted organs of experimental animals, and does not impair the immune response to viruses and immune memory function, with low side effects, and is compatible with CsA, FK506, RAD and other clinical First-line immu...
