Extraction ratios of verapamil after transport studies (20 μM)
across rat jejunal tissue in diffusion chamber experiments in the presence and
absence of 20 μM midazolam, 50 μM ketoconazole, or 20 μM PSC833
Ratios were calculated using eq. 3 based on data collected at t = 180
min. Data represent the mean ± S.D. of n = 6-9
determinations
