Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colon lavage solution that osmotically induces diarrhea to cleanse the colon.
Famotidine is a competitive histamine H2-receptor antagonist that inhibits gastric acid secretion by blocking H2 receptors on parietal cells. Calcium carbonate and magnesium hydroxide act as antacids, neutralizing gastric acid via chemical neutralization.
Oral: 4 L (or 240 mL every 10 minutes) administered the evening before colonoscopy; alternatively, 2 L (or 240 mL every 10 minutes) plus 2 L of clear liquids given in split doses (first 1-2 L evening before, remaining in morning of procedure).
1 tablet (famotidine 10 mg, calcium carbonate 800 mg, magnesium hydroxide 165 mg) orally once or twice daily as needed for heartburn; maximum 2 tablets in 24 hours.

Not applicable; systemic absorption is negligible (plasma levels below detection limits). Clinical effect is localized to gastrointestinal tract.
Famotidine: 2.5-3.5 hours (prolonged in renal impairment, up to 20 hours when CrCl <10 mL/min).
Primarily fecal (approximately 95%) as unabsorbed polyethylene glycol; negligible renal excretion (<5%) as intact polymer.
Famotidine: renal (65-70% unchanged), biliary/fecal (30-35%). Calcium carbonate: feces (unabsorbed calcium), urine (absorbed). Magnesium hydroxide: feces (unabsorbed magnesium), urine (absorbed).
