Strength of mucoadhesion of various devices. Adhesion force between E PO/carbopol devices and porcine intestine was measured. Mucoadhesive devices were incubated with porcine intestine for 30 min in pH 7.4 PBS at 37°C and strength of mucoadhesion was measured as the force required to completely detach the devices from the intestine. E PO devices demonstrated significantly higher mucoadhesive force compared to carbopol devices (p < .05). Data represented as mean ± SE (n = 9)
