NULYTELY-FLAVORED vs POLYETHYLENE GLYCOL 3350
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.
Osmotic laxative. Polyethylene glycol 3350 is a non-absorbable polymer that retains water in the colon via hydrogen bonding, increasing stool water content and stimulating defecation.
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.
17 g (1 capful or packet) dissolved in 4–8 oz (120–240 mL) water, administered orally once daily for constipation; for colonoscopy preparation, 240 g (4 L of solution) ingested at 240 mL every 10–15 minutes.

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.
Terminal elimination half-life is 1-2 hours in patients with normal renal function; prolonged in renal impairment, but clinical impact minimal due to primarily fecal elimination.
Primarily fecal elimination as unabsorbed PEG 3350; minimal systemic absorption (<0.06%). Renal excretion of absorbed fraction is negligible.
Renal: approximately 20% excreted unchanged; Fecal: approximately 80% eliminated unchanged in feces.
