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.
Osmotic laxative: polyethylene glycol (PEG) retains water in the intestinal lumen, increasing stool volume and stimulating peristalsis. Electrolytes (sodium, potassium, chloride, bicarbonate) prevent electrolyte depletion.
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).
Oral: 1 to 2 packets (4 to 8 g of polyethylene glycol 3350) dissolved in 4 to 8 ounces of water once daily, as needed for constipation. Maximum: 2 packets per day.

Not applicable; systemic absorption is negligible (plasma levels below detection limits). Clinical effect is localized to gastrointestinal tract.
Terminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment (up to 20 hours).
Primarily fecal (approximately 95%) as unabsorbed polyethylene glycol; negligible renal excretion (<5%) as intact polymer.
Primarily renal (30-50% unchanged) and biliary/fecal (50-70% as inactive metabolites).
