COLOVAGE vs MIRALAX
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.
Polyethylene glycol 3350 (PEG 3350) is an osmotic laxative that works by retaining water in the stool through hydrogen bonding, increasing fecal water content and promoting bowel movements.
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 oz of water, juice, soda, coffee, or tea, administered orally once daily. Maximum duration of use: 7 days.

Not applicable (non-absorbed, gut lavage); systemic absorption minimal
Not applicable; polyethylene glycol 3350 is minimally absorbed and systemic half-life is not clinically relevant.
Primarily fecal as unabsorbed drug; negligible renal excretion (<5%)
Primarily excreted unchanged in feces (>90% of oral dose); negligible renal elimination (<0.1% recovered in urine).
