Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Osmotic laxative: polyethylene glycol (PEG) retains water in the intestinal lumen, increasing stool volume and stimulating peristalsis. Electrolytes (sodium, potassium, chloride, bicarbonate) prevent electrolyte depletion.
TRILYTE (polyethylene glycol 3350, sodium sulfate, sodium chloride, potassium chloride, sodium ascorbate, ascorbic acid) is an osmotic laxative. The active components induce diarrhea by osmotically drawing water into the gastrointestinal lumen, thereby increasing stool volume and stimulating peristalsis. Sodium ascorbate and ascorbic acid enhance the osmotic effect.
Oral: 1 to 2 packets (4 to 8 g of polyethylene glycol 3350) dissolved in 4 to 8 ounces of water once daily, as needed for constipation. Maximum: 2 packets per day.
Adults: 1 liter (L) orally every 10-15 minutes until 4 L total consumed; complete ingestion within 4 hours.
