Permeability Parameters of Carbamazepine

Parameter	Fresh buccal mucosa	Fresh esophageal mucosa	Frozen buccal mucosa	Frozen esophageal mucosa
J S (mean ± SD) (μg/cm2.h)i	29.203 ± 2.449(a)	27.142 ± 1.879(a)	28.002 ± 0.527(a)	27.312 ± 1.869(a)
T L (mean ± SD) (h)ii	1.090 ± 0.128(ab)	1.185 ± 0.089(b)	0.718 ± 0.071(a)	1.071 ± 0.217(ab)
P (mean ± SD) (cm/h)i	2.92 × 10−2 ± 2.45 × 10−3(a)	2.71 × 10−2 ± 1.87 × 10−3(a)	2.80 × 10−2 ± 5.27 × 10−4(a)	2.73 × 10−2 ± 1.87 × 10−3(a)

ANOVA and SNK tests (p < 0.05) were carried out as appropriate (n = 4). Identical letters mean absence of statistical differences among treatments. Each permeability parameter was analyzed separately

ⁱ F = 0.635, p = 0.619
