Nanotechnology has emerged as a transformative approach in pharmaceutical sciences, providing innovative solutions for drug delivery, therapeutic efficacy, and patient safety. This study reviews the current applications of nanoparticles, liposomes, and nanoemulsions in pharmaceutical formulations, highlighting their role in enhancing solubility, bioavailability, and targeted delivery of drugs. The discussion also addresses technological challenges, manufacturing complexities, and regulatory considerations associated with nanoscale drug systems. Findings indicate that while nanotechnology significantly improves therapeutic outcomes and reduces side effects, careful attention to quality control, stability, and safety is essential for successful implementation. Overall, nanotechnology holds substantial potential to advance personalized medicine and develop safer, more effective pharmaceutical products.
