COLYTE-FLAVORED vs PEG-LYTE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colyte is an osmotic laxative that induces diarrhea by retaining water in the colon through non-absorbable polyethylene glycol (PEG) and electrolytes, resulting in bowel cleansing.
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.
4 liters orally as a single dose or in divided doses for colonoscopy preparation, or 1 liter orally every 10-15 minutes until 4 liters are consumed.

Not applicable; the drug acts locally in the gastrointestinal tract without significant systemic absorption. For the small fraction absorbed, a terminal elimination half-life of approximately 0.5-1 hour is estimated, but clinical relevance is negligible.
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 eliminated in feces (≥95%) as intact drug via the gastrointestinal tract. Minimal systemic absorption; renal excretion accounts for <1% of the administered dose.
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.
