Average gastric pH profile after adding calcium/magnesium carbonate-based antacid or placebo. Average pH profile of six independent repetitions of gastric incubations after adding the calcium/magnesium carbonate-based antacid (Rennie Spearmint, Bayer) or placebo to the gastric medium. a First 5 min of incubation; b changes throughout the entire incubation period (2 h). Throughout the entire incubation, 0.1 N HCl was supplied at 3 mL/min, while gastric emptying was mimicked by removing the content at 1.5 mL/min
