A novel drug delivery system based on Nanostructure Lipid Carriers (NLCs) coated with low molecular weight chitosan (LCH) was developed for the ocular delivery of Acyclovir (ACV) (Seyfoddin and Al-Kassas 2012). The in vitro and in vivo drug release studies from NLCs indicated that the system releases the drug in a controlled manner which could increase the ocular bioavailability of ACV. Moreover, NLCs were found not to be toxic in a number of in vitro eye irritancy assays.
