In vitro effect of pantoprazole on lower esophageal sphincter tone in rats

Figure 2 Relaxation vs Dosage. 5 × 10^-5 mol/L and 1.5 × 10^-4 mol/L pantoprazole sodium induced significant relaxation in lower esophageal sphincter preparations in vitro (^aP < 0.05 and ^bP < 0.001). Each bar represents percent relaxation ± SEM for both control and experiment groups. Numbers in parentheses indicate the number of preparations used from different animals.
