Advancements in Solid Lipid Nanoparticles and Nanostructured Lipid Carriers for Breast Cancer Therapy

Abstract

Solid Lipid Nanocarriers (SLNs) offer a promising avenue for breast cancer treatment, a disease that accounts for 12.5% of global cancer cases. Despite strides in combined therapies (surgery, chemotherapy, radiation, and endocrine therapy), challenges like systemic toxicity, drug resistance, and adverse effects persist. The manuscript offers several novel contributions to the field of breast cancer treatment through the use of SLNs, and these are innovative drug delivery systems, multifunctionality, and biocompatibility, the potential to overcome drug resistance, integration with emerging therapies, focus on personalized medicine, ongoing and future research directions and potential for reduced side effects. SLNs present a novel strategy due to their unique physicochemical properties. They can encapsulate both hydrophilic and hydrophobic drugs, ensuring controlled release and targeted delivery, thus enhancing solubility and bioavailability and reducing side effects. The multifunctional nature of SLNs improves drug delivery while their biocompatibility supports their potential in cancer therapy. Challenges for pharmacists include maintaining stability, effective drug loading, and timed delivery. Combining SLNs with emerging therapies like gene and immunotherapy holds promise for more effective breast cancer treatments. SLNs represent a significant advancement, providing precise drug delivery and fewer side effects, with the potential for overcoming drug resistance. Ongoing research will refine SLNs for breast cancer therapy, targeting cells with minimal side effects and integrating with other treatments for comprehensive approaches. Advances in nanotechnology and personalized medicine will tailor SLNs to specific breast cancer subtypes, enhancing effectiveness. Clinical trials and new treatment developments are crucial for realizing SLNs’ full potential in breast cancer care. In conclusion, SLNs offer a transformative approach to breast cancer treatment, addressing issues of drug delivery and side effects. Ongoing research aims to optimize SLNs for targeted therapy, potentially revolutionizing breast cancer care and providing hope for patients.
