Targeted Drug Delivery Systems for Lung Cancer

In the present scenario, lung cancer is one of the most prevalent and malignant cancer especially among the smoking group of people. The targeted delivery of chemotherapeutic agents to the lungs represents a novel therapeutic approach in lung cancer. Lung is an ideal route for administration of anticancer drug as it provides larger alveolar surface area, low thickness of epithelial barrier & extensive vascularization. Nanoparticles with nanocarriers have possibility of cell-targeted drug delivery with minimal systemic side effect and toxicity. Pulmonary epithelial cell, enzymes, receptors and genes are the target of the targeted drug delivery in lung cancer. This paper reviews the till date targeted drug delivery research performed for the treatment of lung cancer.
