Solid Lipid Nanoparticles: Formulation, Preparation, and Characterization: A Review

The nano drug delivery system has emerged as a novel therapeutic approach for improved efficacy of the existing molecules. Polymeric nanoparticles, lipid based nanoparticles such solid (SLNs), nanostructured carriers, conjugates, ethosomes, liposomes, and self-emulsifying systems are few carriers used delivery. Among SLNs promising in terms biocompatible carrier enhancing bioavailability, controlled release, targeted action. This review explains formulation components SLN, various methods preparation SLNs, characterization parameters SLNs. current successful research on SLN also enlightens. capability drugs increasing can be achieved through future, new directions further improvement expected.
