preparation example Construction

[0023] see figure 1 , the preparation method of the cefdinir granule of one embodiment, comprises the following steps:

[0024] Step S110: mixing the binder, cefdinir, filler and disintegrant to obtain a premix.

[0025] Wherein, binder is povidone. Further, the povidone is selected from one of povidone K12, povidone K15, povidone K17, povidone K25, povidone K30, povidone K60 and povidone K90. Furthermore, the povidone is povidone K30. Specifically, the mass fraction of the adhesive is 2-15 parts. More specifically, the mass fraction of the binder is 3-10 parts.

[0026] Wherein, the mass fraction of propylene glycol is 6-15 parts. Specifically, the mass fraction of propylene glycol is 8-12 parts.

[0027] Among them, the particle size D of cefdinir 90 1 μm to 100 μm. Further, the particle size D of cefdinir 90 10 μm to 70 μm. Specifically, the cefdinir raw material is pulverized by micronization and pulverization technology, and passed through a 100-mesh sieve befor...

Embodiment 1

[0048] The preparation method of the cefdinir composition of the present embodiment is as follows:

[0049] (1) In terms of parts by mass, weigh 100 parts of cefdinir, 660 parts of sucrose, 40 parts of gum arabic, 15 parts of tragacanth gum, 60 parts of dextrin, 60 parts of crospovidone, and 30 parts of povidone K30 60 parts, 60 parts of propylene glycol, 3 parts of orange powder essence, 3 parts of micronized silica gel and 0.1 part of carmine;

[0050] (2) Add cefdinir, sucrose, gum arabic, tragacanth, dextrin, crospovidone, povidone K30 and carmine to the wet granulator for mixing, after mixing evenly, add propylene glycol Carry out granulation to obtain the soft material; then add the soft material to the oscillating granulator and carry out wet granulation through a 30-mesh sieve to obtain wet granules of cefdinir, wherein the granulation time is 180s, and the rotating speed of the stirring paddle is 120rpm, The rotating speed of the cutter is 2100rpm;

[0051] (3) Add ...

Abstract

The invention relates to a cefdinir composition and a preparation method thereof. The preparation method of the cefdinir composition comprises the following steps: mixing an adhesive, cefdinir, a filling agent and a disintegrating agent to obtain a premix; and adding a non-aqueous solvent which is propanediol in the premix to granulate, and drying to obtain the cefdinir composition. In the preparation method of the cefdinir composition, the non-aqueous solvent which is the propanediol is used as a wetting agent, the prepared cefdinir composition is good in stability, the content of related substances of drugs in a shelf life is increased slowly, and thus, the safety of the drugs is ensured effectively.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a cefdinir composition and a preparation method thereof. Background technique [0002] Cefdinir is white or slightly yellow crystalline powder, odorless or slightly odorous; insoluble in water, slightly soluble in 0.1mol / L hydrochloric acid and phosphate buffer solution. Its chemical name is: (-)-(6R,7R)-7-[(Z)-2-(2-amino-4-thiazolyl)-2-hydroxyimino-acetylamino]-8-oxo- 3-vinyl-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid with the formula C 14 h 13 N 5 o 5 S 2 , molecular weight: 395.42, its structural formula is as follows: [0003] [0004] Cefdinir is an oral third-generation cephalosporin with a broad antibacterial spectrum and low toxicity. At present, the oral preparations of cefdinir mainly include capsules, dispersions and granules. Among them, cefdinir granules are more and more widely used clinically because they are more suitable ...
