Abstract

The invention discloses a cefprozil capsule and a preparation method thereof. The cefprozil capsule adopts cefprozil as a main drug; after a provided disintegrating agent is added, and the particle size range is controlled as follows: d50 is more than or equal to 50 micrometers and less than or equal to 120 micrometers, d90 is more than or equal to 75 micrometers and less than or equal to 200 micrometers, and d100 is less than or equal to 300 micrometers. The prepared cefprozil capsule disclosed by the invention has good flowability and a dissolution effect and greatly saves the auxiliary materials. The preparation method disclosed by the invention has the advantages of simple process, easiness for quality control, energy conservation and consumption reduction and is easy to meet the requirement for mass production.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a cefprozil capsule and a preparation method thereof. Background technique [0002] Cefprozil is a second-generation cephalosporin drug with broad-spectrum antibacterial activity. Its chemical name is (6R,7R)-7-[(R)-2-amino-2-(p-hydroxy-phenyl)acetamido]-8-oxo-3-propene-5-thia-1- Azabicyclo(4,2,0)oct-2-ene-2-carboxylic acid monohydrate, the English name is Cefprozil. [0003] Its structural formula is: [0004] [0005] Molecular formula: C 18 h 19 N 3 o 5 S·H 2 o [0006] Molecular weight: 407.45 [0007] Cefprozil is slightly soluble in water (1g can be dissolved in 100~1000ml solvent), the solvent used for the dissolution test of cefprozil preparations stipulated in the 2010 edition of "Chinese Pharmacopoeia" is water 900ml, basket method 100 rpm, 45 minutes Sampling, after filtering, measure the dissolution rate, and the limit is 80% of the la...
