Problems solved by technology

[0007] However, the ordinary wet granulation process of cefixime granules often produces relatively hard particles during the production process, resulting in inability to dissolve quickly, poor suspension of the particles, and often more fine powder particles, which need to pass through Removal by sieving, resulting in low yield of finished cefixime granules and bad taste, which is unfavorable for children to administer

Embodiment 1

[0049] The preparation of embodiment 1 cefixime granules

[0050]

[0051] Process:

[0052] Take cefixime and pass through a 120-mesh sieve, and sucrose, hydroxypropyl cellulose, sodium citrate, citric acid, polyvinylpyrrolidone, neotame, orange essence, and chocolate essence respectively pass through a 60-mesh sieve, and set aside. Dissolve polyvinylpyrrolidone in purified water to prepare a 15% aqueous solution, and set aside.

[0053] Weigh the sieved cefixime, sucrose, hydroxypropyl cellulose, sodium citrate, citric acid and neotame into the fluidized bed for dry mixing and preheat until the material temperature reaches 50°C. The binder solution is sprayed in for granulation. Drying is carried out after the granulation is completed, and the temperature of the material is controlled not to be higher than 60°C for boiling drying. Sieve the dry granules with 10-mesh and 80-mesh sieves, put them into the mixer together with the prescribed amount of sieved orange essence...

Embodiment 2

[0054] The preparation of embodiment 2 cefixime granules

[0055]

[0056] Process:

[0057] Pass cefixime through a 120-mesh sieve, and pass through a 60-mesh sieve for maltodextrin, starch, sodium citrate, citric acid, aspartame, pineapple essence, and sunset yellow, respectively, and set aside. Dissolve polyvinylpyrrolidone in purified water to prepare a 15% aqueous solution, and set aside.

[0058] Weigh the sieved cefixime, maltodextrin, starch, sodium citrate, citric acid, aspartame, and sunset yellow into the fluidized bed for dry mixing and preheat to the material temperature When the temperature reached 45°C, the binder solution was sprayed in for granulation. Drying is carried out after the granulation is completed, and the temperature of the material is controlled not to be higher than 60°C for boiling drying. Sieve the dry granules with 10-mesh and 80-mesh sieves, put them into the mixer together with the prescribed amount of sieved pineapple essence, mix the...

Embodiment 3

[0059] The preparation of embodiment 3 cefixime granules

[0060]

[0061] Process:

[0062] Pass cefixime through a 100-mesh sieve, lactose, sodium bicarbonate, sodium carbonate, stevioside, strawberry essence, and lemon yellow through a 80-mesh sieve respectively, and set aside. Sodium carboxymethyl cellulose was dissolved in purified water to prepare a 5% aqueous solution for subsequent use.

[0063] Weigh the sieved cefixime, lactose, sodium bicarbonate, sodium carbonate, stevioside and lemon yellow into the fluidized bed for dry mixing, preheat until the material temperature reaches 40°C and start spraying Dosage solution for granulation. Drying is carried out after the granulation is completed, and the temperature of the material is controlled not to be higher than 60°C for boiling drying. Sieve the dry granules with 10-mesh and 80-mesh sieves, put them into the mixer together with the sieved strawberry essence of the prescription, mix them evenly, take samples for...

Abstract

The invention relates to the field of pharmaceutical preparations and particularly relates to cefixime granules and a one-step granulation method thereof. The cefixime granules contain the following ingredients in percentage by weight: 1% to 20% of cefixime, 56% to 95% of diluent, 0.5% to 10% of buffer, 0.5% to 10% of binder and 0.1% to 5% of flavoring agent. The cefixime granules have very good quality stability, suspension performance and content uniformity and meanwhile have very good mouth feel, so that the cefixime granules are especially suitable for children and dysphagic people, and the medication compliance is good. The invention further provides a preparation method of the cefixime granules. The one-step granulation preparation method is used, and mixing, granulating and drying are completed in one step in the same fluidized bed, so that the operating step is simple, the production efficiency is high, the preparation method is especially applicable to industrial production.
