Problems solved by technology

Wet granulation is often used in the process. The tablets produced by this method have good hardness and appearance, but there are still the following problems: 1) The drying time is long, the drying temperature is not easy to control, and the soluble components in the drying process can Migrate between particles, resulting in content differences between particles, easy to cause content decline and increase of related substances during storage
2) Montelukast sodium is easy to change color and decompose when exposed to light, which leads to the need to shade it all the time during production, which causes inconvenience to mass production in the workshop
However, this kind of process is rarely used in China, mainly due to the limitation of auxiliary materials and equipment. Only some conventional auxiliary materials are used, and the hardness of plain tablets is not large. During industrial production, there are phenomena of cap dropping, cracking and unqualified brittleness. directly affect the quality of coating

Abstract

The invention belongs to the field of medicine preparations, in particular to a montelukast sodium tablet and a preparation method thereof. Because the montelukast sodium tablet adopts a wet method granulation process and has the problems of long drying time, difficult temperature control and easy causing of content difference, content descent and relevant substance increase between particles, the invention provides the montelukast sodium tablet and the preparation method thereof in order to enhance the stability and the operability of the montelukast sodium tablet. The montelukast sodium tablet provided by the invention comprises montelukast sodium, a filling agent, a disintegrating agent, an adhesive, a colorant, a lubricant and a flow aid. The preparation method of the montelukast sodium tablet provided by the invention adopts direct tabletting after dry method granulation and uses the colorant, the colorant can act as a very good light shielding function in the operational process, the operation is convenient, the influence of a drying process and moist heat to the product quality is avoided, and the product stability is enhanced.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a montelukast sodium tablet and a preparation method thereof. Background technique [0002] Asthma is a chronic inflammatory disease characterized by tracheal hyperresponsiveness and reversible airway obstruction. Leukotrienes are one of the important mediators of bronchial asthma, and they play a key role in the occurrence and development of asthma. Studies have shown that the response it causes is similar to the pathological changes of asthma, whether in vivo or in vitro, and it does not matter in patients with asthma. Period or stable period its level is higher than normal. Leukotriene receptor antagonists have become a new approach in the treatment of asthma. [0003] At present, the incidence rate of asthma in our country is 1%, and the incidence rate of children is as high as 3-5%, which is a significant increase compared with 10 years ago. Drugs us...
