OBJECTIVE: This review aims to explore innovative therapeutic strategies, with a particular focus on recent advancements in drug delivery systems using bioinspired nanomaterials such as solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) for the Idiopathic pulmonary fibrosis (IPF). SIGNIFICANCE OF THE REVIEW: Current treatments for IPF, including the FDA-approved anti-fibrotic agents pirfenidone and nintedanib, primarily aim to slow disease progression rather than reverse fibrosis. Bioinspired nanomaterials like SLNs and NLCs have shown promise in enhancing the efficacy of anti-fibrotic agents by improving drug solubility, stability, and targeted delivery. These systems not only minimize systemic side effects but also maximize therapeutic impact in lung tissues, offering a new hope for improved patient management and outcomes in this debilitating disease. KEY FINDINGS: SLNs facilitate sustained drug release and have demonstrated potential in delivering phosphodiesterase type 5 inhibitors effectively to lung cells. NLCs, on the other hand, exhibit superior biocompatibility and controlled release properties, making them suitable for pulmonary applications. Studies indicate that both SLNs and NLCs can enhance the bioavailability of drugs like ciprofloxacin and montelukast, thereby improving treatment outcomes in pulmonary conditions. CONCLUSIONS: The integration of nanotechnology into anti-fibrotic therapy represents a significant advancement in addressing the challenges posed by IPF. By leveraging the unique properties of SLNs and NLCs, there is potential to overcome the limitations of current treatments and provide new therapeutic options that offer better management and improved outcomes for patients suffering from this debilitating disease.
