Lung-targeted drug delivery to specific disease sites would increase the efficacy of drugs for lung disease, thereby reducing the chances for side-effects in other healthy tissues and organs. Tissue-specific markers have revealed prospective molecular targets that may be used to direct therapies to the lung. Besides the molecular targets, various carriers can be employed to provide active targeting with the help of targeting modules.
