“Mean plasma secretin in the omeprazole group was significantly lower in phases I and III (p less than 0.05).”
“We conclude that 40 mg omeprazole elicits i) a phase-related increase in fasting plasma gastrin, ii) a decrease in secretin in phases I and III, iii) an augmented meal-stimulated gastrin response, and iv) a secretin response characterized by a significantly lower mean in the immediate postprandial period.”
