Description

technical field

[0001] The invention relates to the field of medicine, in particular to a processing technology of cefcapene hydrochloride. Background technique

[0002] Cefcapene pivoxil hydrochloride is used for the treatment of superficial infection caused by sensitive bacteria, deep skin infection, chronic pyoderma, secondary infection of wounds such as trauma, scald and surgical trauma, mastitis, thick around the anus, pharyngitis, laryngitis, Dental tissue infection, periodontitis, etc. At present, cefcapene hydrochloride is generally used in tablets because of the convenience of oral administration. However, cefcapene pivoxil hydrochloride is slightly soluble in ethanol and almost insoluble in water. How to improve its solubility and increase the dissolution rate of tablets has always been a subject of close attention in pharmaceutical preparations.

[0003] For how to process and finish the preparation of a good quality cefcapene pivoxil hydrochloride, there is alm...

Examples

Embodiment 1

[0020] The processing technique of cefcapene pivoxil hydrochloride comprises the following steps:

[0021] (6) Dry raw materials and auxiliary materials so that the moisture content of raw materials and auxiliary materials is ≤3.0%;

[0022] (7) Sieve the raw materials and auxiliary materials through 100 mesh;

[0023] (8) Mix raw materials and auxiliary materials;

[0024] (9) Make granules from raw materials and auxiliary materials that have been processed by powder mixing, and control the moisture content of finishing to ≤3.6%;

[0025] (10) Coating after tableting.

[0026] The particle size of the whole grain in the step (4) is 40 mesh.

[0027] The coating is to heat the tablet core in a coating pot, the temperature of the air inlet is 75° C., and the speed of the coating pot is 4 rpm.

[0028] The exhaust air temperature of the coating is 30°C.

[0029] The coating temperature is 35°C.
