Recent advancements in medical science are reshaping the landscape of pulmonary fibrosis (PF) treatment. PF, a severe lung condition marked by tissue scarring and extracellular matrix accumulation, severely impairs respiratory function and quality of life. Conventional therapies, while slowing disease progression, fall short of reversing or halting fibrosis entirely. In light of this limitation, researchers have turned their focus toward innovative therapeutic strategies. Among these emerging solutions, targeted drug delivery systems (TDDSs) supported by biomaterials offer significant promise. These systems enhance drug specificity and effectiveness while reducing systemic toxicity.

Innovative biomaterials play a pivotal role in advancing TDDSs for PF management. Nanotechnology-based carriers, such as liposomes and polymeric nanoparticles, enable precise drug delivery and sustained release within affected tissues. Hydrogels, with their three-dimensional structures, provide localized and controlled drug administration at sites of inflammation, making them particularly advantageous for PF therapy. Additionally, biological carriers like stem cells and extracellular vesicles contribute to improved outcomes through their biocompatibility and anti-inflammatory properties. Despite their potential, challenges remain in translating these systems into clinical practice due to factors such as immune clearance and platform stability.

The integration of precision medicine with cutting-edge biomaterial research opens new possibilities for overcoming existing barriers in PF treatment. By fostering interdisciplinary collaboration, scientists aim to optimize drug retention and delivery efficiency within diseased tissues. This approach not only addresses current limitations but also paves the way for transformative advancements in patient care. Through advanced drug delivery technologies, the future holds hope for significantly improving the lives of those affected by pulmonary fibrosis.
