Embodiment 1
[0075] The preparation of embodiment 1 granular composition
[0076] The formulation of the granular composition is shown in Table 1.
[0077] Table 1 Prescription of Granular Composition
[0078]
[0079] Preparation of Montelukast sodium granules: Add purified water into a stainless steel bucket, add meglumine and stir until dissolved; continue stirring and add hydroxypropyl-β-cyclodextrin until dissolved, and finally add Montelukast sodium and stir until dissolved. Dissolve to obtain the first binder solution and set aside. Put the mannitol in a wet granulator after passing through a 26-mesh sieve, put the prepared first binder solution in a wet-process granulator, and make soft materials, which pass through a 26-mesh sieve for granulation, and dry at 45°C for 15 Minutes later, pass through a 26-mesh sieve for granulation, continue to dry until the loss on drying is ≤2.0% (IR90°C, dry for 10 minutes), pass through a 26-mesh sieve for granulation, and obtain montelukast...
Embodiment 2
[0082] The preparation of embodiment 2 granular composition
[0083]The formulation of the granular composition is shown in Table 2.
[0084] Table 2 Prescription of Granular Composition
[0085]
[0086] Preparation of Montelukast sodium granules: Add purified water into a stainless steel bucket, add meglumine and stir until dissolved; continue stirring and add hydroxypropyl-β-cyclodextrin until dissolved, and finally add Montelukast sodium and stir until dissolved. Dissolved to obtain the first binder solution, set aside. Mannitol and microcrystalline cellulose 101 were respectively passed through a 26-mesh sieve, mixed evenly and placed in a wet granulator, and the prepared first binder solution was placed in a wet granulator to make soft materials, and the soft materials were passed through Granulate with a 26-mesh sieve, dry at 45°C for 15 minutes, pass through a 26-mesh sieve for granulation, continue to dry until the drying weight loss ≤ 2.0% (IR90°C, dry for 10 mi...
