Site-Targeted Drug Delivery Systems: Polymeric Carriers

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells.

Published on: September 20, 2011

  • Preparation of polymeric nanoparticles using Poly (maleic anhydride-alt-butyl vinyl ether) grafted with monomethoxy poly(ethyleneglycol) (PEG) and 2-methoxyethanol (VAM41-PEG).
  • Loading of Dead Sea Minerals (DSM) into the nanoparticles via a combined miniemulsion/solvent evaporation process.
  • Characterization of nanoparticles for size, morphology, biocompatibility, salt content, and drug release profile.

    • Main Results:

    • Successfully prepared spherical nanoparticles with an average diameter of approximately 300 nm.
    • The nanoparticles exhibited good biocompatibility and a high formulation yield.
    • Demonstrated a time-controlled drug release profile, indicating potential for sustained therapeutic effect.

    Conclusions:

    • The developed DSM-loaded polymeric nanoparticles represent a promising platform for topical drug delivery in dermatology.
    • The nanoparticles offer a biocompatible and efficient system for delivering beneficial Dead Sea Minerals to the skin.
    • The controlled release profile suggests potential for improved treatment efficacy in skin diseases.
