Unit 8: Advanced Nano Drug Delivery Systems
Advanced drug delivery systems utilize nanotechnology, lipid carriers, and self-emulsifying systems to overcome solubility and bioavailability challenges. These approaches include liposomes, niosomes, SNEDDS, and nanoparticles for controlled and targeted drug release.
Definition
Advanced drug delivery systems are innovative formulations designed to improve therapeutic efficacy, enhance bioavailability, and provide controlled or targeted drug release.
These systems overcome limitations of conventional dosage forms such as poor solubility, low permeability, and variable absorption. Common approaches include nanotechnology-based carriers, lipid systems, and self-emulsifying systems.
