LANSOPRAZOLE vs NEXIUM IV
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Proton pump inhibitor that inhibits gastric acid secretion by binding to the H+/K+ ATPase enzyme (proton pump) in gastric parietal cells, preventing the final step of acid production.
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.
15-30 mg orally once daily; 30 mg IV over 30 minutes once daily (when oral not possible).
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.

Clinical Note
moderateDexlansoprazole + Clodronic acid
"The therapeutic efficacy of Clodronic acid can be decreased when used in combination with Dexlansoprazole."
Clinical Note
moderateLansoprazole + Clodronic acid
"The therapeutic efficacy of Clodronic acid can be decreased when used in combination with Lansoprazole."
Clinical Note
moderateDexlansoprazole + Alendronic acid
"The therapeutic efficacy of Alendronic acid can be decreased when used in combination with Dexlansoprazole."
Clinical Note
moderateTerminal elimination half-life: 1.5-2 hours (increased to 3-6 hours in elderly, hepatic impairment).
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 (14-23% as metabolites); biliary/fecal (major route, ~60% as metabolites and parent drug).
Renal (approx. 80% as inactive metabolites), fecal (approx. 20% as metabolites and parent drug). Less than 1% excreted unchanged in urine.
