NULYTELY-FLAVORED vs PEG-LYTE
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-LYTE is an osmotic laxative that induces diarrhea by retaining water in the colon through the non-absorbable polyethylene glycol (PEG) and electrolytes, which prevent dehydration and electrolyte imbalance during bowel cleansing.
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 as a single dose or in divided doses for colonoscopy preparation.

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 is minimally absorbed (<0.06%), thus systemic half-life is not clinically relevant. Local gut transit time ~1-2 hours.
Primarily fecal elimination as unabsorbed PEG 3350; minimal systemic absorption (<0.06%). Renal excretion of absorbed fraction is negligible.
Primarily fecal (98-99%) as unchanged polyethylene glycol (PEG) 3350; negligible renal excretion (<0.2%). Electrolytes (sodium, potassium, bicarbonate) are partially absorbed and excreted renally.
