LANSOPRAZOLE, AMOXICILLIN AND CLARITHROMYCIN (COPACKAGED) vs PROTONIX IV
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lansoprazole is a proton pump inhibitor that irreversibly inhibits the H+/K+ ATPase enzyme system (proton pump) at the secretory surface of gastric parietal cells, suppressing basal and stimulated gastric acid secretion. Amoxicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis. Clarithromycin is a macrolide antibiotic that binds to the 50S ribosomal subunit of susceptible bacteria, inhibiting protein synthesis.
Pantoprazole is a 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.
Each dose: Lansoprazole 30 mg, Amoxicillin 1000 mg, Clarithromycin 500 mg administered orally twice daily for 10-14 days.
40 mg intravenously once daily for 7-10 days; for pathological hypersecretory conditions, initial dose 80 mg IV every 12 hours, titrate per acid output.

Lansoprazole: ~1.5 h (prolonged in hepatic impairment); Amoxicillin: ~1-1.5 h (prolonged in renal impairment); Clarithromycin: ~3-4 h (6-9 h for 14-hydroxy metabolite).
1-2 hours in healthy subjects; prolonged to 3.5-8 hours in hepatic impairment.
Lansoprazole: primarily hepatic metabolism, ~33% renal (metabolites), ~67% fecal; Amoxicillin: ~60-80% renal unchanged; Clarithromycin: ~20-30% renal unchanged, ~50% hepatic metabolism, ~30% fecal.
Primarily hepatic metabolism; 71-82% of dose excreted in urine as metabolites, 18-20% in feces.
