| Outline of Final Research Achievements |
A nanosphere (NS) preparation has been created as a novel and disease-specific DDS preparation of oxime derivatives to develop a disease-specific treatment approach based on a less invasive and more versatile administration technique. A trial product of the NS preparation of oxime derivatives with the average particle size of 100 nm has been produced (in preparation for patent application). In a study, weekly intermittent intravenous administration of the NS preparation of oxime derivatives, repeated oral administration of oxime derivatives, and weekly intermittent intravenous administration of oxime derivatives were comparatively examined in rat models of monocrotaline-induced pulmonary hypertension and coronary total occlusion. As a result, DDS effects of the NS preparation of oxime derivatives have been confirmed. It is suggested that this NS preparation can be a disease-specific therapeutic agent for cardiac failure.
