Mechanism of action
Omeprazole
It is a proton pump inhibitor that suppresses the secretion of gastric acid by inhibiting H+/K+ – ATPase enzymes. It has short plasma half life. It blocks the final step in acid production and thus causes reduction in gastric acidity.
Domperidone
It increases the peristaltic stimulation. It facilitates the gastric emptying and decreases the small bowel transit time by increasing the esophageal and gastric peristalsis. The antiemetic property is related to blocking of dopamine activity.
