PHARMACOKINETIC IMPACT OF TARGETED NANOCARRIERS IN MODERN DRUG DELIVERY SYSTEMS

Drug delivery plays a crucial role in determining the therapeutic effectiveness of pharmaceutical agents. Conventional drug delivery systems often face several limitations such as poor bioavailability, rapid metabolism, non-specific distribution, and increased risk of adverse effects. These challenges can reduce therapeutic outcomes and require frequent dosing, which may decrease patient compliance. To overcome these limitations, targeted nanocarriers have emerged as an advanced strategy in modern drug delivery systems.Targeted nanocarriers are nanoscale drug delivery vehicles designed to deliver therapeutic agents directly to specific tissues or cells. These systems include nanoparticles, liposomes, dendrimers, and polymeric nanocarriers that can encapsulate drugs and protect them from premature degradation in the biological environment. By improving the stability and solubility of drugs, nanocarriers enhance the pharmacokinetic behaviour of therapeutic molecules.Several studies have demonstrated that targeted nanocarriers significantly influence pharmacokinetic parameters such as absorption, distribution, metabolism, and elimination. These carriers improve membrane permeability, prolong systemic circulation time, and enable controlled or sustained drug release. Additionally, targeted delivery allows higher drug accumulation at the disease site while minimizing exposure to healthy tissues, thereby reducing systemic toxicity.Overall, targeted nanocarriers represent a major advancement in modern pharmaceutical technology. Their ability to improve pharmacokinetic properties and enhance therapeutic efficacy offers significant potential for the development of safer and more effective drug delivery systems in the future.
