Effects of drugs on the transport of BB across Caco-2 cell monolayers.

	Papp(A-B, ×10−6)	Papp(B-A, ×10−6)	R = Papp(B-A)/Papp(A-B)
BB	0.146 ± 0.012	1.001 ± 0.049	7.74 ± 1.13
BB + VER	0.337 ± 0.040 ***	0.654 ± 0.020 ***	2.23 ± 0.41 ***
BB + OPCs	0.137 ± 0.021	0.489 ± 0.030 ***	4.10 ± 0.78 **

Data are presented as mean ± SEM of three independent experiments with two transwell inserts each. ** p < 0.01, *** p < 0.001 vs. control (BB alone).
