PEPCID COMPLETE vs RANICLOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Famotidine competitively inhibits histamine at H2-receptors of gastric parietal cells, reducing gastric acid secretion. Calcium carbonate and magnesium hydroxide act as antacids to neutralize existing gastric acid.
Ranitidine is a histamine H2-receptor antagonist that competitively inhibits the action of histamine on parietal cells, thereby reducing gastric acid secretion.
One tablet (famotidine 10mg, calcium carbonate 800mg, magnesium hydroxide 165mg) orally once daily, taken 30 minutes before a meal that causes heartburn.
12.5 mg orally twice daily, increased to 25 mg twice daily after 2 weeks if tolerated; maximum 50 mg twice daily.

2.5-3.5 hours (prolonged to 12-20 hours in severe renal impairment, CrCl <10 mL/min).
Terminal elimination half-life: 8-12 hours (mean 10 hours) in healthy adults; prolonged in renal impairment (up to 20 hours) and elderly.
Renal: 65-70% (famotidine unchanged); fecal: 30-35% (as metabolites). Biliary elimination is minimal (<5%).
Renal: 60-70% unchanged; biliary/fecal: 20-30% as metabolites; <10% in feces as unchanged drug.
