COLYTE WITH FLAVOR PACKS vs POLYETHYLENE GLYCOL 3350
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.
Osmotic laxative. Polyethylene glycol 3350 is a non-absorbable polymer that retains water in the colon via hydrogen bonding, increasing stool water content and stimulating defecation.
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 capful or packet) dissolved in 4–8 oz (120–240 mL) water, administered orally once daily for constipation; for colonoscopy preparation, 240 g (4 L of solution) ingested at 240 mL every 10–15 minutes.

Not applicable (non-absorbed; no systemic absorption, thus no elimination half-life in plasma).
Terminal elimination half-life is 1-2 hours in patients with normal renal function; prolonged in renal impairment, but clinical impact minimal due to primarily fecal elimination.
Primarily fecal (100%) as non-absorbed oral solution; negligible renal or biliary elimination.
Renal: approximately 20% excreted unchanged; Fecal: approximately 80% eliminated unchanged in feces.
