COLYTE WITH FLAVOR PACKS vs MIRALAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colyte is an isotonic solution containing polyethylene glycol 3350 and electrolytes. It acts as an osmotic laxative by retaining water in the colon through non-absorbable polyethylene glycol, resulting in bowel evacuation. The electrolytes prevent significant fluid and electrolyte shifts.
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.
Adults: 4 liters of reconstituted solution administered orally or via nasogastric tube at a rate of 240 mL every 10 minutes, given as a single dose or in divided doses for colonoscopy preparation.
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; no systemic absorption, thus no elimination half-life in plasma).
Not applicable; polyethylene glycol 3350 is minimally absorbed and systemic half-life is not clinically relevant.
Primarily fecal (100%) as non-absorbed oral solution; negligible renal or biliary elimination.
Primarily excreted unchanged in feces (>90% of oral dose); negligible renal elimination (<0.1% recovered in urine).
