LAP Lambert Academic Publishing Lipid-based drug delivery systems are expected as promising oral carriers because of their potential to increase the solubility and improve oral bioavailability of poorly water-soluble and/or lipophilic drugs and are attracting major attention as alternative colloidal drug carriers. Traditional lipid-based formulations include a broad range of lipid solution, emulsions, liposomes, lipid microparticles and nanoparticles. Among the formulations above, the nanostructure lipid carriers (NLCs) are regarded as the second-generation of lipid nanoparticlesThe purpose of this study is to develop an optimized nanostructured lipid carriers (NLC) formulation for Ritonavir, and to estimate the potential of NLC as oral delivery system for poorly water-soluble drugs.
