Nasal delivery has traditionally been restricted to topically acting substances used to treat the common cold and nasal allergies. Recently, however, there has been increased interest in the nose as an alternative to oral delivery and injection for many systemic drugs and vaccines. The highly vascularized and immunogenic nasal mucosa offers potential advantages in terms of quick action, improved bio-availability and patient compliance as well as improved immune response for vaccines.
