Preparation and Application of fluoroquinolones-loaded sustained-release Chitosan Microspheres
摘要
There have been many methods to prepare fluoroquinolones-loaded sustained-release chitosan microspheres, including precipitation, emulsion crosslinking, spray-drying, and ionic gelation. Each of them has its own merits and disadvantages, but the mechanisms underlying drug delivery are basically similar. The prepared drug microspheres can enhance the capacity of anti-fluoroquinolones-resistant bacteria and are primarily used in the anti-inflammation and anti-infection. This paper introduces the preparation methods and sustained drug delivery mechanisms of fluoroquinolones-loaded sustained-release chitosan microspheres and investigates drug delivery characteristics and applications by analyzing, sorting, and summarizing related manuscripts published recently. Fluoroquinolones-loaded sustained-release chitosan microspheres show satisfactory sustained-release and anti-bacterial properties. Therefore, it is of important scientific research and clinical application significance to develop fluoroquinolones-loaded sustained-release nanometer-sized chitosan microspheres.
