Azithromycin (Cephradine, Velosef) is an organic compound with the chemical formula C38H72N2O12, a macrolide antibiotic. It is characterized by resistance to β -lactamase and has a rapid and reliable bactericidal effect on drug-resistant Staphylococcus aureus and many other bacteria that are resistant to broad-spectrum antibiotics.
Polyethylene glycol, abbreviated as "PEG". It is a polymer compound formed by dehydration and condensation of ethylene glycol between molecules. Chemical formula HOCH2 (CH2OCH2) nCH2OH. Among them, n is greater than 4. The average molecular weight is between 200 and 7000. The number after polyethylene glycol represents the average molecular weight of the product. For example, polyethylene glycol-400 indicates that the average molecular weight of polyethylene glycol in this product is about 400.

Carrageenan is white or light brown particles or powder, odorless or slightly smelly, sticky and smooth taste. Soluble in about 80 ° C water, forming a viscous, transparent or slightly milky white easy to flow solution.
Glycine magnesium is in the form of white powder and is soluble in water but insoluble in ethanol. The in vitro simulated digestion test shows that when the magnesium content reaches 14%, it has a high bioavailability. During the preparation process, pure natural raw materials are used, and the process flow complies with green environmental protection requirements and is suitable for industrial production.
