Development and Evaluation of Acitretin Loaded Solid Lipid Nanoparticles for Topical Drug Delivery System

Abstract

In order to understand the in vitro drug release of the produced gel, the goal of the current investigation was to construct and characterize. Acitretin loaded Solid Lipid Nanoparticles (ActSLNs). Act SLNs were created utilizing the Box Benhken design and the hot homogenization procedure. Act SLN's average diameter and surface morphology were assessed. Act SLNs were lyophilized, then they underwent stability testing, powder X-Ray diffraction, Differential Scanning Calorimetry (DSC), and Fourier Transform Infrared (FT-IR) tests to characterize them. The SLNs were added to a 0.25% w/w Carbopol 940 gel base the Stability study, ex vivo drug release in vitro drug releases in rat skin were carried out. The optimized Act SLNs had a spherical form, an entrapment efficiency of 78.82% to 85.73%, and an average particle size of 123.24nm to 409nm. The generation of SLNs was confirmed by DSC, FTIR, and XRD data. ActSLN gel (0.056mg/cm2) significantly increased the amount of accutane deposited in rat skin compared to Act plain gel (0.012mg/cm2).No discernible change was found in the stability studies, according to stability studies.
