A concise review on preparation methods used for the development of solid lipid nanoparticles

  • Vasu Deva Reddy Matta Dr. Reddy’s Laboratories Ltd., Bachupally, Hyderabad, Telangana State, India


Solid lipid nanoparticles (SLNs) are in submicron size range nanoparticles and are made of biocompatible and biodegradable materials (mainly composed of lipids and surfactants) capable of incorporating both lipophilic and hydrophilic drugs. SLNs are also considered as substitute to other colloidal drug systems, also used as controlled systems and targeted delivery. SLNs can be considered as an alternative for oral drug delivery vehicle to improve the oral bioavailability of drugs, associated reduction of drug toxicity and stability of drug in both GIT and plasma. There are different techniques used for the preparation of SLNs. Generally, the preparation of SLNs and any other nanoparticle system necessitates a dispersed system as precursor; otherwise particles are produced through the use of a particular instrumentation. This review provides the summary on the techniques or methods used for the development of SLNs of poorly water soluble drugs for improved drug delivery.
