Omeprazole is a proton pump inhibitor (PPI) that works by irreversibly blocking the hydrogen/potassium ATPase enzyme system in gastric parietal cells. This action suppresses the final step of stomach acid production, providing potent and long-lasting relief from acid-related symptoms and allowing esophageal and stomach tissue to heal.
Verdict
Highly effective for short-term acid-related disease; long-term use requires medical supervision.
