Prospects of Natural Polymers based Nano-drug Delivery Systems in the Treatment of Pulmonary Disorders

Numerous lung conditions, including lung cancer, influenza, acute respiratory distress syndrome, chronic obstructive pulmonary disease (COPD), asthma, and pneumonia, present a great threat to people all over the world. A range of pharmaceutical drugs, peptides, antibodies, and genetic therapies have all been used to treat chronic lung illnesses. Unfortunately, the majority of chronic lung disorders cannot be fully cured by medication alone. At the moment, managing the symptoms is the only asthma treatment. This article provides a brief overview of the state-of-the-art understanding of the function of natural polymeric materials and emphasises recent developments in innovative drug delivery systems that may help treat a variety of lung diseases. Furthermore, the paper also discusses the latest application of natural polymeric materials for targeting gene delivery through different approaches.
