Experimental Models for Buccal and Sublingual Drug Absorption Including Epithelial Cell Multilayers and Monolayers

  • Alan Rogerson
Part of the NATO ASI Series book series (NSSA, volume 218)


Like the skin the oral mucosa is constantly exposed to the environment thus its fundamental property is probably a barrier function. Pathogens and other potentially harmful materials, which may be borne in air, water or food, are excluded by the stratified epithelial cell layers, which seem to be more closely related to skin than to the columnar epithelia of the gastrointestinal tract (Squier and Johnson, 1975). Thus while the barrier properties are important in the resistance of disease they may also compromise potential drug absorption via the buccal or sublingual routes.
