Solid Lipid Nanoparticles For Drug Delivery Research Articles

Solid Lipid Nanoparticles

Solid lipid nanoparticles (SLNs) are produced from physiologically biocompatible lipids. They have been proven to improve solubility, cellular uptake, and stability, reduce enzyme degradation, and prolong the circulation time of various drugs. SLNs have been applied in the oral, parenteral, transdermal, intranasal, ocular, and pulmonary drug delivery of different drugs, with enhanced safety, bioavailability, and overall therapeutic effects. In this entry, the authors summarize the primary features of SLNs, methods to prepare SLNs, and recent applications of SLNs in drug delivery. Owing to their advantages, SLNs are potential drug delivery systems to improve the management of various diseases and will, soon, be available for clinical use.

Excipients, drug release mechanism and physicochemical characterization methods of Solid lipid nanoparticles

From last thirty years, solid lipid nanoparticles (SLNs) gain much importance as drug delivery vehicle for enhanced delivery of the drugs, proteins, nutraceuticals and cosmetics. SLNs defined as a submicron size range nanoparticle with below 1000 nm and are mainly composed of lipids and surfactants, capable of incorporating both lipophilic and hydrophilic drugs. SLNs also used as controlled systems, targeted delivery and altered therapeutic efficacy purpose. A wide variety of methods such as double emulsion, solvent evaporation, ultra sonication, high-pressure homogenization and microemulsion used for SLNs production. This review provides the significance of SLNs in drug delivery with highlighting on selection of excipients, drug release mechanism, principles and limitations associated with their physicochemical and surface morphological characterization.
