This is a fictional article abstract provided to serve as an example. Actual articles on drug delivery systems may have variations in content and structure. The field of drug delivery has witnessed significant advancements in recent years, aiming to enhance therapeutic outcomes, minimize side effects, and improve patient compliance. Conventional drug delivery systems, such as oral tablets and injections, have been the backbone of pharmaceutical interventions. However, they often face challenges related to poor bioavailability, inadequate targeting, and unfavorable pharmacokinetics. To overcome these limitations, researchers have explored innovative approaches and technologies in drug delivery systems.

Discussion

This review article provides an overview of the recent advancements in drug delivery systems, highlighting both conventional and emerging strategies. The conventional approaches, including oral, transdermal, and parenteral routes, are discussed in terms of their advantages and limitations. Additionally, novel approaches such as nanoparticle-based delivery systems, implantable devices, and targeted drug delivery systems are explored. Nanoparticle-based drug delivery systems have gained significant attention due to their ability to improve drug solubility, stability, and targeting. Various nanoparticles, including liposomes, polymeric nanoparticles, and metallic nanoparticles, have been utilized to encapsulate and deliver drugs to specific target sites. The article explores the principles behind these systems and their applications in the treatment of various diseases [4-7].

Implantable devices, such as drug-eluting stents and implantable pumps, offer localized and sustained drug release, reducing the need for frequent dosing (Figure 1). The article discusses the design and applications of implantable drug delivery systems, including their use in the treatment of chronic conditions. Targeted drug delivery systems aim to deliver drugs directly to the site of action, minimizing systemic exposure and reducing side effects. This article provides an overview of various targeting strategies, including passive targeting through enhanced permeability and retention effect, as well as active targeting using ligand-receptor interactions [8-10].
