| Outline of Final Research Achievements |
In this study, we aimed the development of new drug delivery system using targeted liposomes for the treatment of choroidal neovascularization.Different vascular targeted liposomes were administrated via eye drops or subconjunctival injection in the laser-induced CNV rat model, and the one that reached the choroid membrane was selected. Rho-kinase inhibitor, fasudil, was encapsulated in the selected liposomes using the remote loading method (liposomal fasudil).After the suspension of of liposomal fasudil was dropped into eyes of the model animal, the amount of fasudil in the ocular tissue was measured using high performance liquid chromatography. We could confirm the signal of fasudil in the choroid. Furthermore, eye drop administration of liposomal fasudil inhibited CNV creation in the model.These results suggested that liposome fasudil may be a potential therapeutic agent for age-related macular degeneration.
