Serum phosphorus level following coadministration of lanthanum carbonate hydrate and calcium carbonate. Temporal transition at (a) pH 2 and (b) pH 7. Area under the curve from 0 to 2 h (AUC0–2 h) of serum phosphorus level at (c) pH 2 and (d) pH 7. Each dot shows the mean value ± standard error, and each column shows the mean value + standard error of 8–12 cases at pH 2 (12 cases for normal, 10 cases for control, 9 cases for lanthanum carbonate hydrate, 8 cases for calcium carbonate, and 8 cases for combination) and 10–12 cases at pH 7 (12 cases for normal, 11 cases for control, 12 cases for lanthanum carbonate hydrate, 10 cases for calcium carbonate, and 12 cases for combination)
