Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine at H2 receptors on gastric parietal cells, inhibiting gastric acid secretion.
H2-receptor antagonist; competitively inhibits histamine at H2 receptors of gastric parietal cells, reducing basal and stimulated gastric acid secretion.
20 mg intravenously over at least 2 minutes or as an infusion over 15-30 minutes every 12 hours; alternatively, 20 mg orally once or twice daily.
300 mg orally twice daily for 14 days; alternative: 600 mg orally once daily for 14 days.

2.5-3.5 hours (normal renal function); prolonged to 20-30 hours in severe renal impairment (CrCl <10 mL/min). Clinical context: dose adjustment required in renal insufficiency.
2-3 hours (prolonged to 4-5 hours in elderly or renal impairment, CrCl <30 mL/min)
Renal (65-70% unchanged by tubular secretion); minor biliary/fecal elimination (<30%). Clearance correlates with creatinine clearance.
Renal: 60% unchanged; fecal: 35% (mainly metabolites)
