Preparation and Comparatively Evaluation of Phenylethyl Resorcinol-Loaded Nanocarriers: Nanoemulsions and Nanostructured Lipid Carriers

Abstract

The aim of the present study was to prepare nanostructured lipid carriers (NLCs) and nanoemulsions (NEs) with different lipid compositions for delivery of phenylethyl resorcinol (PR) and investigate the effect of the lipid composition on the performance of lipid-based nanocarriers. The optimized nanocarriers were evaluated by photon correlation spectroscopy (PCS), Laser diffraction (LD), encapsulation efficiency, in vitro release and in vitro penetration studies. The particle sizes of all the freshly prepared nanocarriers were in the range of 70-200 nm. PR-NLCs showed higher encapsulation efficiency than PR-NEs. A controlled-release behavior of PR-NLCs was observed in in vitro release studies. In vitro penetration studies demonstrated nanocarriers with smaller particles possessed higher penetration ability. According to the present study, nanocarriers with small particle sizes can be considered as a potential drug delivery system for typical application.

“…At the same time, some of these nano drug-loading systems have entered clinical trials [12]. Then, the ensuing problem is the growing demand to establish efficient and functional nanocarriers to deliver PR in cells [13].…”
