Abstract

Nanoparticle drug delivery systems (NPDDS) promise to increase the efficacy and safety of therapeutic agents, yet achieving controlled and sustained release of active ingredients from these nanoparticles remains a significant challenge hindering the full realization of this technology’s benefits. This paper aims to uncover the key problems associated with nanoparticle drug release by delving into the fundamental concepts and mechanisms underlying this intricate process. Drug release mechanisms like diffusion, erosion, and stimuli-responsive release are intricately examined, while critically evaluating the obstacles posed by factors such as particle size, surface properties, drug-carrier interactions, and physiological barriers. Some of the effects of not achieving controlled and sustained release are burst release and incomplete release, as well as premature drug release and instability. Future directions and strategies for improved drug release are proposed, including nanoparticle design and engineering, stimuli-responsive nanoparticle, and hybrid nanoparticle systems. By synergistically addressing the key problem of nanoparticle drug release through this comprehensive approach, the full potential of this transformative technology can be unlocked, paving the way for more effective and safer therapeutic interventions, ultimately leading to improved patient outcomes and reduced healthcare costs.
