Convective inhibitor washout requires a very high concentration of a membrane-impermeant inhibitor in the intestinal lumen for antisecretory efficacy. (A) Computations done for human mid-jejunal anatomy as in Fig. 2. Percent inhibition of net secreted fluid as a function of Co/Kd for indicated Jvo. Jvo of ∼7 × 10−2 µL/cm2/s is typical in cholera. (B) Computations done for human colonic anatomy with long, narrow crypts without villi. Percent inhibition of net secreted fluid as a function of Co/Kd for indicated Jvo. Jvo of ∼7 × 10−3 µL/cm2/s in colon is typical in cholera.
