Preparation of solid lipid nanoparticles through various methods using different precursors

Abstract

Now a day there has been exponential increase in interest in developing nanoparticles for novel drug delivery system. Nanoparticles provide many advantages over conventional drug delivery system like improved pharmacokinetic property; enhance bioavailability, smaller drug dose required for the treatment. Recently solid lipid nanoparticles (SLN) materialized as novel approach to oral and parenteral drug delivery system. SLN possess a solid lipid core that can solubilise lipophilic drug. Lipid core was stabilised by using surfactant (emulsifier). SLN can be prepared by using various precursors like emulsion, micro emulsion, and SLM can be prepared by using lipid coated microcrystal. These precursors further proceed to obtain particles of desired size and shape by making use of various techniques and equipment’s. Each precursor show benefits along with some limitations.
