Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Proton pump inhibitor. Suppresses gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells.
Lansoprazole 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. This action is dose-related and leads to inhibition of both basal and stimulated gastric acid secretion.
40 mg orally once daily for 8 weeks for erosive esophagitis; 40 mg intravenously once daily for 7-10 days for GERD with esophagitis.
30 mg intravenous infusion over 30 minutes once daily for up to 7 days; may switch to oral therapy when patient can tolerate oral intake.

Terminal elimination half-life: ~1 hour (range 0.5–2 h); clinically, acid suppression lasts longer due to covalent binding to proton pumps
Terminal elimination half-life is approximately 1.5–2 hours in healthy individuals; however, the pharmacodynamic half-life (duration of acid suppression) is longer (up to 24 hours) due to accumulation in parietal cell canaliculi.
Renal: ~71% as metabolites; fecal: ~18% via bile; unchanged renal excretion: <1%
Primarily hepatic metabolism via CYP2C19 and CYP3A4; approximately 75% excreted in urine as metabolites, with less than 1% as unchanged drug; about 20% eliminated in feces via bile.
