This update review is on mucoadhesive polymers used in nasal dosage forms. The nasal
mucosa provides a potentially good route for systemic drug delivery. One of the most
important features of the nasal route is that it avoids first-pass hepatic metabolism, thereby
reducing metabolism. The application of mucoadhesive polymers in nasal drug delivery
systems has gained to promote dosage form residence time in the nasal cavity as well as
improving intimacy of contact with absorptive membranes of the biological system. The …
