  • Title: Solid lipid nanocarriers in drug delivery: characterization and design.
    Author: Mu H, Holm R.
    Journal: Expert Opin Drug Deliv; 2018 Aug; 15(8):771-785. PubMed ID: 30064267.
    Abstract:
    INTRODUCTION: Solid lipid nanoparticles are promising drug carriers for systemic circulations as well as local applications. One of the major challenges for drug delivery is designing nanocarriers for efficient delivery of active substances to the target site and facilitating drug absorption. AREAS COVERED: In this article, the effects of excipients and particle preparation methods on the properties of solid lipid nanocarriers (SLNCs) and their impact on drug absorption and efficacies related to different administration routes are reviewed and discussed. EXPERT OPINION: SLNCs have special characteristics, making them attractive as drug delivery systems, for parenteral and oral delivery for systemic effects, or ocular, pulmonary and topical delivery to enhance local treatment efficacy and reducing systemic side effects. Both excipients and fabrication methods are crucial for the function and size of nanoparticles and should be considered simultaneously in designing particles to obtain the optimal drug absorption and efficacy, especially for local treatments. Despite the demonstrated advantages by the preclinical studies, further studies on improved understanding of the interactions of SLNCs with biological tissues of the target site is necessary for efficient designing functional nanoparticles for clinical applications.
