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.
PEG 3350 is an osmotic agent that causes water retention in the colon, leading to bowel evacuation. Electrolytes (sodium sulfate, potassium chloride, magnesium sulfate, sodium bicarbonate) prevent significant electrolyte shifts.
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 liter (provided as powder for reconstitution) administered at a rate of 240 mL every 10 minutes until rectal effluent is clear or 4 liters total is consumed. Typically given as split-dose: half the volume the evening before and half the morning of colonoscopy.

Not applicable; systemic absorption is negligible (plasma levels below detection limits). Clinical effect is localized to gastrointestinal tract.
Not applicable; PEG 3350 is not significantly absorbed and does not have a systemic half-life. The colon transit time is approximately 1 hour after ingestion.
Primarily fecal (approximately 95%) as unabsorbed polyethylene glycol; negligible renal excretion (<5%) as intact polymer.
Primarily fecal elimination of unabsorbed PEG 3350; negligible systemic absorption <0.06%. Electrolytes are excreted renally and fecally.
