Raju Yadav, Shweta Gogate*, Rita Morya, Somesh Kumar Saxena
ABSTRACT
This review examines recent advances in microencapsulation techniques for pharmaceutical applications, highlighting their crucial role in improving drug delivery systems. Microencapsulation involves enclosing active pharmaceutical ingredients within protective matrices, enhancing stability, bioavailability, and release kinetics. This article discusses various techniques including coacervation, spray drying, and fluidized bed coating, analyzing their mechanisms, materials, applications, and challenges. Current trends reveal a shift toward stimuli-responsive systems, nanotechnology integration, and personalized medicine approaches. Despite promising developments, challenges in scale-up, cost, and regulatory hurdles remain. Future directions point toward smarter, more targeted delivery systems that optimize therapeutic efficacy while minimizing side effects.
