| titleOfInvention |
Intravenous nanoparticles for targenting drug delivery and sustained drug release |
| abstract |
Provided are poly(lactic-co-glycolic acid) (PLGA) and poly(lactic acid) (PLA) nanoparticles that encapsulate a low molecular weight and water-soluble drug and can deliver the drug to target legion sites where the particles gradually release the drug over a prolonged period of time. The nanoparticles are prepared by allowing the low-molecular, water-soluble and non-peptide drug to interact with a metal ion so as to make the drug hydrophobic, encapsulating the hydrophobicized drug into PLGA or PLA nanoparticles, and allowing a surfactant to be adsorbed onto the surface of the particles. |
