Solid lipid nanoparticles (SLN) have been sought as alternative carriers for therapeutic agents it is administered by parenteral, oral, nasal and pulmonary routes. The research works in this area suggest that optimized conditions is required to incorporate hydrophobic or hydrophilic drugs and seem to fulfil the requirements for an optimum particulate carrier system. Solid lipid nanoparticles (SLNs) have been proposed as suitable colloidal carriers for delivery of drugs with limited solubility. Several obstacles frequently encountered with many compounds, with poor specificity and stability are at least partially overcome by delivering them using SLN.In this review it is intended to discuss the recent advances, various method of preparartion,methods of evaluation, various routes of administration, stability and pharmaceutical applications of SLN were discussed.
