RECENT ADVANCES IN PHARMACEUTICS: NOVEL DRUG DELIVERY SYSTEMS AND EMERGING TECHNOLOGIES

Abstract

Pharmaceutics is a rapidly evolving discipline that focuses on the design, formulation, and delivery of therapeutic agents to achieve optimal therapeutic outcomes. Conventional drug delivery systems, although widely used, often suffer from limitations such as poor bioavailability, nonspecific distribution, rapid drug degradation, and systemic toxicity. These challenges have driven significant advancements in modern pharmaceutics, particularly in the development of novel drug delivery systems (NDDS) and advanced pharmaceutical technologies. Recent innovations in nanotechnology, biomaterials, polymer science, and biotechnology have revolutionized the way drugs are formulated and delivered in the human body.

Nanotechnology-based drug delivery systems such as liposomes, polymeric nanoparticles, dendrimers, and micelles have demonstrated significant improvements in drug solubility, stability, and targeted delivery. These systems allow controlled release of drugs at specific sites, thereby enhancing therapeutic efficacy while minimizing adverse effects. Additionally, sustained and controlled release formulations have improved patient compliance by reducing dosing frequency and maintaining stable plasma drug concentrations.

Emerging technologies such as stimuli-responsive drug delivery systems, 3D-printed pharmaceuticals, and biopharmaceutical innovations including monoclonal antibodies, gene therapy, and mRNA-based therapeutics have further expanded the scope of pharmaceutics. These advancements have enabled personalized medicine approaches and precision drug delivery strategies.

Despite these advancements, challenges such as scalability, regulatory approval, toxicity concerns, and manufacturing complexity remain significant barriers. However, ongoing research in nanomedicine, smart drug delivery systems, and computational pharmaceutics is expected to overcome these limitations. This review highlights recent developments, applications, challenges, and future perspectives in modern pharmaceutics and drug delivery science.
