Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells.
Proton pump inhibitor (PPI) that suppresses gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells. Esomeprazole is the S-isomer of omeprazole, which is concentrated in the acidic environment of parietal cells and converted to the active sulfenamide form that binds covalently with the proton pump, leading to irreversible inhibition.
30 mg orally once daily for 4-8 weeks; for non-erosive GERD, 30 mg orally once daily for 4 weeks; for erosive esophagitis, 60 mg orally once daily for up to 8 weeks; for maintenance of healed EE and relief of heartburn, 30 mg orally once daily. Administer without regard to food; dissolve tablet in water.
20-40 mg intravenously once daily; for GERD with erosive esophagitis: 20-40 mg once daily; for Zollinger-Ellison syndrome: 80 mg IV every 12 hours, adjust based on acid output.

Terminal elimination half-life is approximately 1-2 hours; however, the pharmacodynamic half-life (duration of acid suppression) is prolonged due to accumulation in parietal cell canaliculi.
Terminal elimination half-life is approximately 1-1.5 hours in healthy adults. In patients with hepatic impairment (Child-Pugh Class A, B, or C), half-life may be prolonged up to 2.9-8 hours.
Renal (approx. 53% as metabolites, <2% as unchanged drug), biliary/fecal (approx. 47%).
Renal (approx. 80% as inactive metabolites), fecal (approx. 20% as metabolites and parent drug). Less than 1% excreted unchanged in urine.
