  • Publication number: 20130338569
    Abstract: A polymeric hydrogel composition is described for the delivery of a pharmaceutically active agent when an electrical stimulus is applied to the composition. The composition comprises a polymer which forms the hydrogel, such as poly vinyl alcohol (PVA) cross-linked with diethyl acetamidomalonate (DAA), an electroactive polymer such as polyaniline and a pharmaceutically active agent such as an analgesic, and in particular, indomethacin. The composition can be subcutaneously implanted at a targeted site and under normal conditions, the active agent will be entrapped in the hydrogel itself. However, upon the application of an electric current to the hydrogel, the active agent will be released. When the electric current is removed, the change is reversed and the active agent will cease to be released. In one embodiment of the invention, the hydrogel composition is for use in alleviating chronic pain.

    Abstract: The present invention comprises poly(vinyl benzoate) nanoparticle suspensions as molecular carriers. These nanoparticles can be formed by nanoprecipitation of poly(vinyl benzoate) in water using Pluronic F68 as surfactant, to create spherical nanostructures measuring about 200-250 nm in diameter which are stable in phosphate buffer and blood serum, and only slowly degrade in the presence of esterases. Kinetics experiments in phosphate buffer indicate that 78% of the coumarin-6 was encapsulated within the polymer matrix of the nanoparticle, and the residual 22% of coumarin-6 was surface-bound and quickly released. The nanoparticles are non-toxic in vitro towards human epithelial cells (IC50>1000 ?g/mL) and primary bovine primary aortic endothelial cells (IC50>500 ?g/mL), and exert non-observable bactericidal activity against a selection of representative test microbes (MIC >250 ?g/mL).
