Abstract

The nasal cavity has a large surface and a rich blood supplied mucosa. Drugs absorbed by blood vessels pass directly into the systemic circulation, thereby avoiding first-pass metabolism. Numbers of factors limit the intranasal absorption of drugs, especially peptide and protein drugs. These factors are the epithelial and mucus barrier, the rapid mucociliar clearance and the enzymatic activity. Increasing the residence time of the drug formulation in the nasal cavity and a period of contact with nasal mucosa, may improve drug absorption. Approaches to increase the residence time of drug formulations in the nasal cavity usually involve the use of microspheres, liposomes and bioadhesive gels.
