Abstract

The aim of this work was to produce and characterize solid lipid nanoparticles (SLN) containing levothyroxine sodium for oral administration, and to evaluate the kinetic release of these colloidal carriers. SLNs were prepared by microemulsion method. The particle size and zeta potential of levothyroxine sodium-loaded SLNs were determined to be around 153 nm,−43 mV (negatively charged), respectively by photon correlation spectroscopy. The levothyroxine entrapment efficiency was over 98 %. Shape and surface morphology were determined by TEM and SEM. They revealed fairly spherical shape of nanoparticles.SLN formulation was stable over a period of 6 months. There were no significant changes in particle size, zeta potential and polydispersity index and entrapment efficiency, indicating that the developed SLNs were fairly stable.
