Researchers explore the potential of nanocarriers to enhance the efficacy of Traditional Chinese Medicines
Traditional Chinese Medicines (TCMs) have a long history of use in treating various ailments, but their effectiveness has often been limited by challenges in drug delivery. However, a recent review published in the Journal of Nanobiotechnology highlights the potential of nanotechnology-based delivery systems to overcome these obstacles. By utilizing nanocarriers such as liposomes, polymeric and inorganic nanoparticles, and organic/inorganic nanohybrids, researchers aim to improve the solubility, bioavailability, and safety of TCMs, leading to better therapeutic outcomes and fewer adverse effects.
Role of nanoparticles in TCM drug delivery:
Nanocarriers have emerged as a promising strategy to enhance the bioavailability and targeted action of TCMs. Lipid nanoparticles, such as liposomes, solid lipid nanoparticles (SLNs), and nanostructured lipid carriers (NLCs), offer advantages such as improved drug stability, higher bioavailability, and controlled release. These lipid-based carriers can alter pharmacokinetics, reduce toxicity, and enhance the therapeutic index of TCMs. Additionally, microemulsions (MEs) and nanoemulsions (NEs) provide flexible drug delivery platforms with increased specific surface area, while polymer hydrogel-based systems offer targeted and sustained delivery of hydrophilic and hydrophobic TCMs.
Structural illustration of applications in nanodrugs of TCMs:
Inorganic nanocarriers, including gold nanoparticles (Au NPs) and mesoporous silica nanoparticles (MSNs), have customizable properties such as size and surface charge, making them ideal for drug delivery. Organic and inorganic nanohybrids combine the benefits of both materials, offering high stability, safety, and intelligent drug release. Prodrug-based nanocarriers have shown promise in anticancer drug delivery, with increased drug availability, high loading efficiency, and controlled release. Self-assembled nanomedicines have also demonstrated anticancer efficacy, opening up new avenues for cancer therapy.
Challenges and Future Considerations:
While nanocarrier-based delivery methods show great potential, there are still challenges to overcome. Liposomes, SLNs, and polymeric micelles (PMs) have limited clinical efficacy, but coupling them with other nanoparticle platforms could enhance their performance. Polymeric vesicles offer an attractive platform for TCMs but require further research to optimize their manufacturing process. Inorganic nanocarriers face challenges related to in vivo biocompatibility and stability, necessitating the optimization of surface chemistry and functionalization techniques. Furthermore, the use of nanocarriers in nanomedicine may increase toxicity, immunogenicity, and production costs, requiring careful consideration.
Conclusion:
The use of nanotechnology-based delivery systems has the potential to revolutionize TCM drug delivery, offering higher bioavailability, decreased toxicity, and improved therapeutic efficacy. However, further research is needed to expand the scope of application, deepen the theoretical knowledge base, and address fundamental research gaps. The development of TCM-based nanomedicines requires constant innovation in delivery methods and manufacturing technologies, as well as advancements in supporting technologies like artificial intelligence and single-cell sequencing. With continued efforts and advancements, nanocarrier-based delivery systems could pave the way for the clinical application of TCMs in the near future.
