Apparent permeability, Papp, of a variety of paracellularly and transcellularly transported drugs. In general, paracellular transport was increased for cells on eECM with decreased CBD and decreased stiffness, while transcellular transport was unaffected. Caco-2 cells demonstrated enhanced Papp of the paracellularly absorbed ranitidine (Zantac®), nadolol (Corgard®), and atenolol (Tenormin®). No difference in transport was observed for transcellularly absorbed dexamethasone (Decadron®) and naproxen (Aleve®). *p < 0.05, **p < 0.01, ***p < 0.001.
