BRAIN-TARGETED SOLID LIPID NANOPARTICLES CONTAINING RILUZOLE: PREPARATION, CHARACTERIZATION AND BIODISTRIBUTION
2009
Aim: Developments within nanomedicine have revealed a great potential for drug delivery to the brain. In this study nanoparticulate systems as drug carriers for riluzole, with sufficiently high loading capacity and small particle size, were prepared to a reach therapeutic drug level in the brain. Materials & method: Solid lipid nanoparticles containing riluzole have great potential as drug-delivery systems for amyotrophic lateral sclerosis and were produced by using the warm oil-in-water microemulsion technique. The resulting systems obtained were approximately 88 nm in size and negatively charged. Drug-release profiles demonstrated that a drug release was dependent on medium pH. Biodi…
NANOSTRUCTURED LIPID CARRIERS CONTAINING RILUZOLE AND PHARMACEUTICAL FORMULATIONS CONTAINING SAID PARTICLES
2008
The present invention concerns the preparation, the physical-chemical, technological and pharmaceutical characterization of Riluzole-loaded nanoparticle vectors. The chosen production technology permitted to obtain these systems in a reproducible way, with high yields and low costs. In particular, a novel formulation of Riluzole loaded into lipid nanoparticles was developed which is able to carry to the Central Nervous System a higher amount of drug in comparison with the free drug. In vivo results demonstrated that the administration on rats of these formulation permits to obtain a lower deposit of Riluzole in organs such as liver, spleen, heart and kidneys; the consequence is a reduction …

Biocompatible polymeric micelles with polysorbate 80 for use in brain targeting.
2008
In this paper, the synthesis and characterization of novel amphiphilic graft copolymers based on an alpha,beta-poly(N-2-hydroxyethyl)-D, L-aspartamide (PHEA) backbone and D, L-polylactic acid (PLA) hydrophobic side chains are reported. These copolymers were obtained starting from PHEA-ethylenediamine (PHEA-EDA), which was functionalized with polysorbate 80 (PS(80)) and/or PLA in order to obtain the PHEA-EDA-PS(80)-PLA and PHEA-EDA-PLA samples, respectively. The degrees of derivatization, DD(PS80) and DD(PLA), of PHEA-EDA-PS80-PLA, calculated by (1)H-NMR, resulted in being 1.2 +/- 0.03 mol% and 0.54 +/- 0.05 mol%, respectively, while that of PHEA-EDA-PLA was found to be 0.60 +/- 0.05 mol%.
