Average a cumulative and b instantaneous increase in gastric pepsin activity with antacid or placebo. The graphs reflect the concentration of digested peptide/protein fractions due to the action of pepsin on a reference protein (bovine serum albumin) during antacid or placebo incubations (n = 6) (absorbance values at 280 nm). Graphs on the left focus on the first 5 min of incubation, while those on the right show the changes throughout the entire incubation period
