Problems solved by technology

Although Chinese patent application 200510061861.1 discloses the use of sweeteners and flavoring agents to mask the bitterness to ensure patient compliance and the use of polymer binders to enhance the stability of azithromycin dry suspension, there is no teaching or It suggests how to effectively mask the bitter taste in azithromycin suspension granules to ensure the patient's medication compliance, improve the suspension uniformity and stability of the suspended granules, and the prior art does not provide a method suitable for masking the bitter taste to ensure the patient's compliance. Adjuvants and dosages of azithromycin suspension granules that improve drug compliance, suspension uniformity and stability of suspension granules, and do not provide any information about azithromycin suitable for improving hygroscopicity and preparation formability.

Abstract

The invention relates to an azithromycin suspension granule and a preparation method thereof. The invention adopts appropriate auxiliary materials and dosages thereof to prepare the azithromycin suspension granules by using an appropriate preparation method. The azithromycin suspension granule provided by the invention is characterized in that: the components of the azithromycin suspension granule is (by weight portion): azithromycin 100-250, sucrose 500-1250, starch 60-150, mannite 16-40, steviosin 20-50, appropriate ethanol with a mass percentage of 95 percent and appropriate coconut flavor. The azithromycin suspension granule provided by the invention tastes good and the bitterness thereof is effectively covered, thus ensuring the compliance of the sufferer to take the medicine; the azithromycin suspension granule also has the advantages of good suspension homogeneity, high formability and stability.

Description

technical field [0001] The invention relates to azithromycin suspension granules and a preparation method thereof, belonging to the technical field of medicine. Background technique [0002] Azithromycin is an off-white crystalline powder, odorless, bitter in taste, slightly hygroscopic, and easily decomposed under acidic conditions. Its chemical name is: (2R, 3S, 4R, 5R, 8R, 10R, 11R, 12S, 13S, 14R)-13-[(2,6-dideoxy-3-C-methyl-3-O-methyl Base-α-L-nucleo-hexapyranosyl)oxy]-2-ethyl-3,4,10-trihydroxy-3,5,6,8,10,12,14-heptamethyl-11 -[[3,4,6-trideoxy-3-(dimethylamino)-β-D-xyl-hexapyranosyl]oxy]-1-oxa-6-azacyclopentadecane-15 -ketone. [0003] Its structural formula is as follows: [0004] [0005] Molecular formula: C 38 h 72 N 2 o 12 [0006] Molecular weight: 749.00 [0007] The research and development of azithromycin began with the discovery of erythromycin in the early 1950s. It is the most commonly used anti-infective drug in clinical practice. It has a good ...
