LIPID-POLYMER HYBRID NANOCARRIERS AS A NOVEL DRUG DELIVERY PLATFORM

Abstract

The main aim of my review to discuss the most prominent nanocarrier, “Lipid-Polymer Hybrid Nanoparticle” (LPHNPs) that overcomes the limitation of lipid and polymeric nanoparticles. That consists of polymeric core and lipid outer layer. The polymeric core encapsulates both hydrophilic and hydrophobic drugs and lipid shell provides a coat that gives a barrier to prevent drug leakage and easily penetrate into the skin. The LPHNPs has significant application in drug delivery, drug targeting, cancer treatment, brain drug delivery, multiple drug delivery, delivery of diagnostic imaging agent and Small interfering Ribonucleic acid (siRNA). This session is based on literature information in which LPHNPs were prepared by Two-step and Single-step method. Most of the researcher use the Single-step method by emulsification solvent evaporation and Nanoprecipitation method that are easy to prepare LPHNPs. The Polylactic Glycolic acid (PLGA), Poly € caprolactone, Chitosan, Alginate, Dextron, Sodium Alginate, etc used as polymeric core and Stearic Acid, Palmitic Acid, Cetyl Alcohol, Behenol Alcohol, etc used as lipid core. All results were analyzed by us according to the literature and authors’ expertise. The drug release depends on diffusion processes, followed by erosion, then swelling of the matrix. The lipid shell provides a biocompatible shield that acts as the phospholipid bilayer of skin and easily penetrates into the skin. That also capable to deliver the multidrug and diagnostic imaging agent for the treatment of cancer. The Lipid-Polymer Hybrid Nanoparticles are the most prominent nanocarrier for drug delivery. That is capable to deliver both Hydrophilic and Lipophilic drugs and show high bioavailability.
