COLOVAGE vs GLYCOLAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
COLOVAGE is a bowel cleansing preparation containing polyethylene glycol 3350 and electrolytes. It acts as an osmotic laxative, causing fluid retention in the colon to stimulate bowel evacuation.
Osmotic laxative. Polyethylene glycol (PEG) increases intraluminal water volume in the colon by osmosis, promoting stool passage and relieving constipation.
4 liters of PEG-3350 electrolyte solution orally as a single dose for colon cleansing prior to colonoscopy; alternatively, 2 liters with ascorbic acid regimen.
17 g (1 heaping tablespoon) dissolved in 4-8 ounces of liquid once daily, orally.

Not applicable (non-absorbed, gut lavage); systemic absorption minimal
Not applicable due to negligible systemic absorption; local colonic transit time approximately 2-4 hours.
Primarily fecal as unabsorbed drug; negligible renal excretion (<5%)
Minimally absorbed; excreted primarily unchanged in feces via osmotic action. Renal excretion negligible (<0.2% absorbed dose).
