Serum phosphorus level following coadministration of PA21 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 7–12 cases at pH 2 (7 cases for normal, 11 cases for control, 12 cases for PA21, 11 cases for calcium carbonate, and 11 cases for combination) and 7–10 cases at pH 7 (10 cases for normal, 8 cases for control, 10 cases for PA21, 8 cases for calcium carbonate, and 7 cases for combination)
