Problems solved by technology

[0007] The currently disclosed montelukast sodium tablets adopt direct powder-mixing and wet granulation technology, and under the condition of no additives in the prescription, it is easy to lead to a decrease in content and an increase in related substances, etc.
The samples prepared by the above two processes were compared with "Singulair "Compared with imported products, the dissolution curves in the dissolution medium of pH 6.8 and water are similar, but the dissolution curves in the dissolution medium of pH 1.0 and pH 4.5 are similar to those of "Singulair "Imported products are not similar, and there may be a risk of non-equivalence in bioequivalence tests

Abstract

The invention relates to a rapidly-dissolving and stabile montelukast oral solid preparation and a preparation method thereof, wherein the preparation uses montelukast as a raw material drug, is added with a diluents, a disintegrating agent, an additive, an adhesive and a lubricant as auxiliary materials, and uses a pharmaceutically acceptable preparation technology. The preparation and the preparation technology can raises a dissolving speed of the oral preparation, enables the oral preparation to substantially raise the dissolving speed in a dissolving mediums of pH1.0 and pH 4.5, and can raises the medicament stability.

Description

technical field [0001] The invention relates to a leukotriene receptor antagonist montelukast sodium oral solid preparation and a preparation method thereof. Background technique [0002] Montelukast sodium is a leukotriene regulator developed and marketed by Merck. It is widely used in the prevention and long-term treatment of bronchial asthma, exercise-induced asthma, and allergic rhinitis, especially in pediatric respiratory diseases. It is the only long-acting control drug that can be used alone in addition to inhaled hormones for asthma treatment at home and abroad in recent years. [0003] Montelukast sodium is a potent and selective leukotriene D4 receptor antagonist, which can selectively inhibit various stimuli (sulfur dioxide, exercise and cold air, etc.) and various allergens (pollen, dander, etc.) etc.) caused by the increase of inflammatory factor leukotriene polypeptide, thereby inhibiting the immediate phase and delayed phase inflammatory response, reducing o...
