Preparation and Evaluation of Niosomes for the Delivery of Antioxidant to the Skin for Antiaging Purpose

Abstract

Niosomes are unilamellar or multilamellar vesicles capable of entrapping hydrophilic and hydrophobic solutes. Niosomes are promising drug carriers as they possess greater stability. Niosomes is currently reported to increase drug stability, and increase the penetration of the adsorbed compound across the skin. Thus noisome could be incorporated in semisolid formulation. Quercetin niosomes were prepared by using Cholesterol, Span 80/ Span 85 as surfactants, chloroform, and diethyl ether using ether injection method. Formulation was then evaluated for particle size, drug content, entrapment efficiency, and in-vitro drug release studies. Niosomal Gel Prepared by Carbopol 934P and characterized as Drug Content, in-vitro Cumulative Drug Release and viscocity. Quercetin released from the Plain Gel to 68.64 in 8 hrs. The skin permeation increase of quercetin drug was recorded from vesicle Gel in comparison to plain gel and antioxidant activity performed by DPPH Method. The results showed that quercetin has considerable whitening and antioxidant capacities and Span80+85(1:2) Niosomes remarkably improved the solubility and photostability of quercetin. Furthermore, compared to quercetin solution, quercetin-niosomes had the advantages of sustained release and improved transdermal penetration. Niosomal Gel storage under refrigeration showed greater stability. The results suggested that Niosomes could better promote the transdermal delivery of quercetin, by their ability to control drug release.
