Nanotechnology-Driven and Personalized Dosage Formulations: Emerging Approaches for Optimizing Drug Efficacy and Minimizing Adverse Effects

Nanotechnology-driven and personalized dosage formulations represent a transformative advancement in pharmaceutical sciences, offering innovative solutions for improving drug efficacy, safety, and patient-specific therapeutic outcomes. Conventional drug formulations often face challenges such as poor solubility, low bioavailability, non-specific distribution, frequent dosing requirements, and undesirable side effects. Nanotechnology has emerged as a powerful approach to overcome these limitations through the development of nanoscale drug delivery systems capable of targeted and controlled drug release. Simultaneously, personalized medicine has shifted healthcare toward individualized treatment strategies based on genetic, physiological, and environmental factors. The integration of nanotechnology with personalized dosage formulations enables precise drug delivery, optimized pharmacokinetics, reduced toxicity, and enhanced therapeutic effectiveness. Nanocarriers such as liposomes, polymeric nanoparticles, dendrimers, nanocrystals, and lipid-based systems have demonstrated significant potential in improving the delivery of therapeutic agents. Personalized dosage forms further contribute to treatment success by tailoring drug selection and dosing regimens to individual patient characteristics. This paper explores recent developments in nanotechnology-based drug delivery systems and personalized pharmaceutical formulations, emphasizing their role in maximizing therapeutic efficacy while minimizing adverse effects. Future perspectives, challenges, and clinical implications are also discussed in the context of advancing precision medicine and patient-centered healthcare.
