Preparation and physicochemical characterization of topical quercetin loaded liposome

Background: The use of herbal extracts in recent years has been of great interest to researchers around the world. Quercetin antoxidant properties play an important role in various fields of health. Objective: Due to the low skin permeability and poor solubility in aqua media, quercetin liposome formulation has been used to obtain topical use of this substance. Methods: In this study, liposomal quercetin was prepared by fusion method and the physicochemical characteristics of the formulation, including particle size, incorporation efficiency and in vitro drug release were evaluated. Results: The particle size of formulations were between 7.68 to 58.1 nm. The incorporation efficiency of formulations were in range of 80.55 to 96.80 percent. In vitro drug release of formulations were about 60 to 70 percent. Conclusion: According to the results obtained, it can be said that the use of this substance as a liposomal formulation can improve physicochemical properties of the drug in the laboratory conditions and provide it as a suitable candidate for further in vivo and clinical studies.
