INTRODUCTION

In the ever-evolving field of healthcare, the development of efficient drug delivery systems plays a vital role in improving patient outcomes. Traditional approaches to medication administration have often relied on systemic delivery methods, resulting in suboptimal therapeutic efficacy and undesirable side effects (Hartemann P, 2011). However, recent advancements in drug delivery systems have paved the way for more targeted, controlled, and personalized approaches to drug delivery. These innovative drug delivery systems have the potential to revolutionize healthcare by enhancing the efficacy of medications, minimizing adverse effects, and improving patient compliance (Paul M, 2016). They enable precise dosing, sustained release, and localized delivery of pharmaceutical substances, ensuring that therapeutic agents reach their intended targets with optimal efficiency. Various types of drug delivery systems have emerged as groundbreaking solutions in recent years. Injectable drug delivery systems, for instance, have undergone significant improvements (Errico ME, 2002). Biodegradable polymers and nano-carriers now enable sustained and controlled release of drugs, reducing the frequency of administration and enhancing patient compliance. Moreover, the integration of smart injectable systems with sensors and feedback mechanisms allows for precise dosing and real-time monitoring, leading to personalized medicine tailored to individual patient needs. Transdermal drug delivery systems have also witnessed remarkable progress (Banci L, 1999). These systems utilize patches or gels to deliver drugs through the skin and into the bloodstream. Recent advancements have enhanced their permeation capabilities, allowing for the delivery of a wider range of drugs (Downing M, 2018). Additionally, the development of microneedle arrays and skin-penetrating nanoparticles has improved drug absorption, ensuring precise and controlled release. Implantable drug delivery systems have gained traction as well, offering sustained and controlled release of drugs over an extended period. These devices, often made of biocompatible materials, are directly implanted into the body to target specific tissues or organs (Abraham GA, 2003). Recent breakthroughs include the use of microfluidic technologies for precise control of drug release rates and the development of remotely controlled devices for personalized therapy adjustments. Inhalable drug delivery systems have proven particularly effective for respiratory conditions. These systems provide a direct route to the lungs, ensuring targeted delivery of medications (Heberer T, 2002). Recent advancements have led to the development of dry powder inhalers and nebulizers with improved drug dispersion and connectivity options for realtime monitoring of patient response. Furthermore, the integration of nanotechnology in drug delivery systems has opened up new frontiers. Nanoparticles and nanocarriers can be engineered to encapsulate drugs, enhancing their solubility, stability, and targeted delivery to specific tissues (Peterjack LR, 2006). Surface modifications enable the attachment of ligands for targeted drug release, increasing therapeutic efficacy while minimizing off-target effects. The potential of nanotechnology in personalized medicine and combination therapy holds great promise for the future. The continuous advancements in drug delivery systems are reshaping the landscape of healthcare (Chu CC, 2002). These innovative technologies are improving patient outcomes, revolutionizing medication administration, and paving the way for personalized, efficient, and patientcentric treatment modalities. As researchers and scientists push the boundaries of drug delivery, we anticipate a future where precision medicine becomes the norm, leading to better therapeutic outcomes and improved quality of life for patients worldwide (WC Li, 2014).
