Development Of Targeted, Statin Loaded Nanoparticle Delivery Systems, Stephanie Judkins

Master's Theses

Statins lower endogenous production of cholesterol through their inhibition of the mevalonate pathway. Lipophilic statins in particular exhibit anti-inflammatory effects at supraphysiological doses by preventing downstream signaling through small molecule GTPases. Interest lies in development of statins as anti-inflammatory therapeutics, however, achieving effective doses locally incurs serious off-target effects. Our goal was to develop and optimize a targeted delivery system to traffic these drugs to inflamed sites and unload the drug at effective concentrations while avoiding systemic exposure. Lipophilic statins (lovastatin, simvastatin, and atorvastatin) were incorporated into polymeric nanoparticles (NPs) due to their hydrophobicity. We have shown that statins released …
