Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexlansoprazole is a 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 a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+ ATPase at the secretory surface of gastric parietal cells.
30 mg orally once daily for up to 8 weeks; for healing esophagitis, 60 mg orally once daily for up to 8 weeks; maintenance 30 mg orally once daily.
20-40 mg orally once daily; for erosive esophagitis, 40 mg once daily for 4-8 weeks. IV: 20-40 mg once daily over 10-30 minutes.

Terminal elimination half-life is 1–2 hours in healthy subjects, but due to prolonged gastric acid suppression via irreversible binding to proton pumps, duration of action exceeds 24 hours. Half-life is not directly correlated with pharmacodynamic effect.
Terminal elimination half-life is approximately 1–1.5 hours in healthy individuals, but may be prolonged to 2–3 hours in poor metabolizers (CYP2C19) or patients with hepatic impairment. The effect on gastric acid secretion persists for 24 hours due to irreversible binding to proton pumps.
Renal (approximately 50% as inactive metabolites) and fecal (approximately 50% as inactive metabolites).
Approximately 80% of a dose is excreted as metabolites in urine, with the remainder (about 20%) eliminated in feces via biliary excretion. Less than 1% is excreted unchanged in urine.
