The past three decades have seen the emergence of the nasal mucosa as a viable alternative route for drug delivery. The availability of over 15 drugs meant for systemic action is a testament to its rapidly growing popularity. However, the absence of a good in vitro model precludes the rapid screening of suitable drug compounds and the investigation of molecular processes involved in nasal drug delivery. Although animal-derived nasal mucosal explants are popular, comparisons of their transport properties to humans has not been studied. Currently, a cell culture system derived from normal human tracheal/bronchial epithelial cells (EpiAirway™ system) is being investigated for its utility in drug transport studies.
