GLYCOLAX vs NULYTELY-FLAVORED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Osmotic laxative. Polyethylene glycol (PEG) increases intraluminal water volume in the colon by osmosis, promoting stool passage and relieving constipation.
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.
17 g (1 heaping tablespoon) dissolved in 4-8 ounces of liquid once daily, orally.
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.

Not applicable due to negligible systemic absorption; local colonic transit time approximately 2-4 hours.
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.
Minimally absorbed; excreted primarily unchanged in feces via osmotic action. Renal excretion negligible (<0.2% absorbed dose).
Primarily fecal elimination as unabsorbed PEG 3350; minimal systemic absorption (<0.06%). Renal excretion of absorbed fraction is negligible.
