Embodiment 1

[0044] prescription:

[0045]

[0046]

[0047] Preparation:

[0048] 1) Micronizing the montelukast sodium bulk drug to obtain micronized montelukast sodium with a particle size of 80 μm;

[0049] 2) Put the pregelatinized starch in cold purified water and stir well until it is completely dissolved into a solution to obtain a pregelatinized starch solution;

[0050] 3) Weigh mannitol and micronized montelukast sodium according to the prescription amount, mix the two, then add to the pregelatinized starch solution obtained in step 2), stir well until the mannitol dissolves, and the montelukast The sodium is uniformly dispersed; then cooled under vacuum, and aspartame is added at the same time to obtain a suspension;

[0051] 4) Put the suspension obtained in step 3) into blister holes in divided doses, put it into a vacuum freeze-drying box for freeze-drying, and finally seal the drug-filled blister to obtain montelukast sodium freeze-dried orally disintegrating tablet...

Abstract

The invention belongs to the technical field of medicine, and particularly relates to a montelukast sodium preparation and a preparation method thereof. The montelukast sodium preparation is freeze-dried orally-disintegrating tablets, and 1,000 freeze-dried orally-disintegrating tablets are prepared from 5 g of montelukast sodium, 80-120 g of pregelatinized starch, 150-200 g of mannitol, an appropriate amount of aspartame and 1,200-1,500 ml of purified water. The montelukast sodium freeze-dried orally-disintegrating tablets have good stability and rapid disintegration, and the purpose that tablets prepared by means of a freeze-drying method need to have high physical strength, disintegration performance and hygroscopicity is achieved.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a montelukast sodium preparation and a preparation method thereof. Background technique [0002] Asthma is a common respiratory disease, which is related to allergic constitution and genetic factors. Asthma is a type I hypersensitivity disease, and its pathogenesis is mainly due to the release of active mediators, such as leukotrienes, histamine and prostate, which cause bronchospasm and pulmonary ventilation disorders. Induces degranulation of mast cells and basophils. Asthma is a world-recognized medical problem, and is listed as one of the four major persistent diseases by the World Health Organization. According to the survey, there are at least 20 million asthmatics in my country, and the symptoms related to asthma mainly include cough, expectoration, wheezing, dyspnea, and chest tightness. The typical manifestation is paroxysmal expiratory dyspnea accompani...
