Abstract

The invention discloses an azithromycin dry suspension and a preparation method thereof. The azithromycin dry suspension is prepared from the following raw materials in parts by weight: 100 parts of azithromycin, 55-65 parts of sodium citrate, 85-95 parts of sodium carboxymethylcellulose, 1700-1750 parts of powdered sugar and 24-28 parts of an orange flavor, wherein the azithromycin is taken as a main drug, the sodium citrate is taken as a flocculating agent, the sodium carboxymethylcellulose is taken as a suspending agent, the powdered sugar is taken as a suspending agent and a flavoring agent and the orange flavor is taken as a flavoring agent. The prepared azithromycin dry suspension is excellent in various detection results, especially relatively low in content of related substances and excellent in settlement volume ratio, the drug effect of the azithromycin can be better developed, the effective rate of the drug is improved, the azithromycin dry suspension has sweet taste, regurgitation caused by a too bitter drug is avoided and the azithromycin dry suspension is suitable taking by children, old people and kinds of groups.

Description

technical field [0001] The invention relates to the technical field of azithromycin, in particular to a dry suspension of azithromycin and a preparation method thereof.
