Abstract

Abstract : Curcumin is an important anti-inflammatory natural compound with low bioavailability which is due to poor solubility and absorption. Solid lipid nanoparticles (SLNs) loaded with Curcumin were formulated and evaluated for physical parameters and in vitro/ex vivo permeation. Further the optimised SLN was assessed for pharmacokinetic/pharmacodynamic considerations. SLNs were formulated by emulsion-solvent evaporation technique and evaluated for physical properties and in vitro drug release. Selected SLNs were evaluated for stability and then characterised for pharmacokinetic parameters and anti-inflammatory activity with reference to a commercial formulation. Spherical SLNs were obtained in the size range of 102–156 nm with negative potential. C-SLN category has shown highest entrapment efficiency. The order of drug release was S-SLN > G-SLN > C-SLN. Selected SLN formulation C-SLN-3 has shown good stability under various conditions. C-SLN-3 has demonstrated highest drug permeation through human skin and 171.623 mg drug content permeated in 24 h. It has also shown lowest lag time 0.375 h. Similarly, it has shown maximum value for Cmax in in vivo determination and increased the bioavailability upto 68.12%. C-SLN-3 provided 90.75% edema inhibition in 6 h. Present study shows that nature of lipids and its physical-chemical properties are critical for SLN formulation and can be used for designing better drug delivery systems with optimum transdermal permeation.
