NULYTELY-FLAVORED vs PEG 3350 AND ELECTROLYTES
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
NULYTELY-FLAVORED is an osmotic laxative containing polyethylene glycol (PEG) 3350 and electrolytes. It induces diarrhea by retaining water in the colon through osmotic action, thereby cleansing the bowel.
PEG 3350 is an osmotic laxative that retains water in the bowel lumen via hydrogen bonding, increasing fecal water content and stimulating peristalsis. Electrolytes (sodium sulfate, potassium chloride, sodium bicarbonate, magnesium sulfate) prevent significant fluid and electrolyte shifts by maintaining isotonicity.
Adult dose: 4 liters of reconstituted solution orally as a single dose, or 240 mL (8 oz) every 10 minutes until 4 liters are consumed, approximately 1-1.5 hours before colonoscopy.
4 liters orally of the reconstituted solution administered as a single dose at 240 mL every 10 minutes or 1 to 1.5 L/hour until rectal effluent is clear. Alternatively, 240 mL every 10 minutes until 4 L consumed.

Not applicable; PEG 3350 is not significantly absorbed and does not exhibit a terminal elimination half-life in the systemic circulation. Clinical effect is due to local osmotic action in the gut.
Not applicable; PEG 3350 undergoes minimal systemic absorption (<0.2%), thus no meaningful terminal half-life. Systemic half-life of absorbed fraction is <2 hours.
Primarily fecal elimination as unabsorbed PEG 3350; minimal systemic absorption (<0.06%). Renal excretion of absorbed fraction is negligible.
Primarily fecal (96–98%) as unabsorbed PEG 3350; electrolytes absorbed are excreted renally (sodium, potassium) and via feces (biliary excretion negligible).
