Abstract: Azithromycin dry suspension is one of the most commonly used drugs in pediatric clinic, but its taste masking has been difficult to achieve. 5 representative products of azithromycin dry suspension were chose to compare their tastes both using electronic tongue and human sensory evaluation methods, and there existed the differences of bitterness, later bitterness, graininess, and adhesion among these products. Raman micro-imaging was used to determine the difference in taste mainly due to different prescription ingredients and manufacturing techniques. Through mixing the dry suspensions with alkaline mixing solvent, the bad taste of each product was masked after evenly dispersing in the solvent, and their tastes were all close to the taste of the solvent. In the future, it is planned to investigate the stability and bioavailability of the solvent preparations, and then to give the medication suggestion of solvent preparation after ensuring their efficacy.
