Nanotechnology-Based Formulations in Pharmaceutical Research: Challenges and Future Prospects

Abstract

Nanotechnology has become one of the most promising tools in pharmaceutical research, offering innovative strategies for targeted and controlled drug delivery. This paper reviews the design, formulation, and evaluation of nanocarriers such as liposomes, polymeric nanoparticles, dendrimers, and solid lipid nanoparticles. Nanotechnology enhances drug solubility, stability, and bioavailability while reducing systemic side effects. The discussion extends to critical formulation challenges such as aggregation, sterilization, scale-up feasibility, and regulatory approval. Moreover, in-vitro and in-vivo testing parameters for nanomedicines are examined to establish bioequivalence and safety. The industrial applicability of nanotechnology in oncology, neurology, and infectious diseases is highlighted through recent case studies. The paper also emphasizes the need for interdisciplinary collaboration among chemists, pharmacists, and bioengineers to address formulation complexities. The future of pharmaceutical nanotechnology lies in integrating artificial intelligence-driven design and green synthesis for sustainable drug development.
