COLYTE WITH FLAVOR PACKS vs PEG-LYTE
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.
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.
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.

Not applicable (non-absorbed; no systemic absorption, thus no elimination half-life in plasma).
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 (100%) as non-absorbed oral solution; negligible renal or biliary elimination.
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.
