Embodiment Construction

[0023] Further description will be given below through specific examples.

[0024] The present invention successfully prepares an instant azithromycin oral suspension through prescription screening, process optimization and long-term and short-term preparation stability tests.

[0025] One, the preparation method of instant azithromycin oral suspension

[0026] 1) Preparation of azithromycin suspension powder

[0027] Weigh 60g of oral azithromycin raw material, 175g of diluent, and 15g of sodium bicarbonate, mix them in equal increments, and sub-package them into 2.5g / packages, each containing 600mg of oral azithromycin raw material.

[0028] 1) The diluent involved in the above can be water-soluble auxiliary materials such as glucose, sucrose, lactose, xylitol, mannitol, etc. as required, and can be one of them, or a mixture of several in any proportion. The purpose of adding it is to dilute the azithromycin so that it can be easily subpackaged and uniformly dispersed in t...

Description

technical field [0001] The invention relates to a preparation method of an antibiotic preparation, in particular to a preparation method of an instant azithromycin oral suspension. Background technique [0002] Azithromycin is a broad-spectrum antibiotic obtained by modifying the chemical structure of erythromycin. It was originally developed by Yugoslav SourPliva Company. It has broad antibacterial spectrum, stable acid, good absorption, high bioavailability, long half-life, low toxicity and resistance. Good acceptance and so on. It is suitable for all kinds of people, especially children and the elderly. Domestic and foreign literature reports involve oral dry suspensions, microsphere dry suspensions, vesicles, gels, taste-masking enteric-coated sustained-release microspheres, etc. Common pediatric preparations on the domestic market include dry suspensions and Granules, without azithromycin oral suspension. However, in the clinical and working practice of pediatrics, i...
