Emerging Trends in Transdermal Drug Delivery: Nanoparticle Formulations and Technologies for Enhanced Skin Penetration and Drug Efficiency

Transdermal drug delivery systems (TDDS) have emerged as a popular non-invasive approach for treating skin-related disorders, offering quick and reliable drug delivery into the skin, thereby accelerating therapeutic efficacy. In India, there is a growing interest in TDDS due to its perceived safety and effectiveness. Researchers are actively developing new formulations and technologies to enhance drug delivery efficiency and reduce side effects. Recent trends indicate a focus on overcoming challenges such as low permeability and stability issues through innovative nanoparticle-based delivery systems. Nanotechnology has revolutionized transdermal drug delivery by offering precise control over nanoparticle properties, enabling enhanced skin permeation and targeted delivery. Various nanoparticle formulations, including polymeric nanoparticles, liposomes, nanotubes, solid lipid nanoparticles, and nanoemulsions, have shown promise in improving drug solubility, bioavailability, and sustained release. Additionally, microneedles have emerged as a successful transdermal delivery method, offering advantages over traditional creams and patches. Metallic nanocarriers and nanoemulsions are also being explored for their potential in targeted drug delivery and enhanced skin penetration. Despite these advancements, challenges such as toxicity and biocompatibility need to be addressed for widespread clinical translation. Overall, the growing interest in transdermal drug delivery systems in India reflects the potential for improved therapeutic outcomes and patient convenience through innovative nanoparticle-based formulations and technologies.
