| titleOfInvention | Montelukast sodium crystal and its preparation method and pharmaceutical composition |
| abstract | The invention belongs to the field of chemistry and medicine, and in particular relates to montelukast sodium crystals and a preparation method and application thereof. The technical problem to be solved by the present invention is that the amorphous montelukast sodium has low purity, high hygroscopicity and low temperature stability. The solution of the present invention to solve the above-mentioned technical problems is to provide a montelukast sodium crystal that has not been reported in the prior art. The present invention also provides the preparation method and application of the above-mentioned montelukast sodium crystal. The montelukast sodium crystal provided by the invention has higher purity, no hygroscopicity and high temperature stability. |
