SOLID LIPID NANOPARTICLES AND NANO LIPID CARRIERS: AS NOVEL SOLID LIPID BASED DRUG CARRIER
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2011, Vol 2, Issue 2
Abstract
Interest in lipid based drug delivery has developed over the past decade fuelled by a better understanding of the multiple roles lipids may play in enhancing oral bioavailability. Moreover, the emergence of novel excipients with acceptable regulatory and safety profiles coupled with advances in formulation technologies have greatly improved the potential for successful lipid based formulations. Solid lipid nanoparticles (SLN) introduced in 1991 represent an alternative carrier system to traditional colloidal carriers, such as emulsions, liposomes and polymeric micro- and nanoparticles. SLN combine advantages of the traditional systems but avoid some of their major disadvantages. This paper reviews the present state of the art regarding production techniques for SLN/ nanostructured lipid carrier (NLC), drug incorporation method and types, stability. The potential of SLN/NLC to be exploited for the different administration routes is also highlighted.
