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.
Lansoprazole: Proton pump inhibitor that irreversibly inhibits H+/K+ ATPase in gastric parietal cells, reducing gastric acid secretion. Naproxen: Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis.
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.
Lansoprazole 15 mg plus naproxen 250 mg orally twice daily.

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.
Naproxen: 12-17 hours (terminal), allows twice-daily dosing. Lansoprazole: 1-2 hours (terminal), but acid suppression persists due to accumulation in parietal cells.
Renal (approx. 53% as metabolites, <2% as unchanged drug), biliary/fecal (approx. 47%).
Naproxen: Renal (95% as unchanged drug and metabolites, primarily 6-O-desmethyl naproxen), fecal (<5%). Lansoprazole: Renal (20% as metabolites), fecal (80% as metabolites).
