POLYMER-SURFACTANT NANOPARTICLES FOR SUSTAINED RELEASE OF COMPOUNDS

摘要

A polymer-surfactant nanoparticle formulation, using the anionic surfactant aerosol OT (AOT) and polysaccharide polymer alginate, is used for sustained release of water-soluble drugs. The AOT-alginate nanoparticles are suitable for encapsulating doxorubicin, verapamil and clonidine, as well as therapeutic agents effective against dermal conditions such as psoriasis. The nanoparticles are also suitable for encapsulating photo-activated compounds such as methylene blue for use in photo-dynamic therapy of cancer and other diseases, and for treating tumor cells that exhibit resistance to at least one chemotherapeutic drug.
