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.
Osmotic laxative; induces bowel cleansing by retaining water in the intestinal lumen via osmotic effects, increasing intraluminal pressure and stimulating peristalsis.
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.
Oral: 3 packets (each containing 17.5g sodium sulfate, 3.13g potassium sulfate, and 1.6g magnesium sulfate) dissolved in water as a single dose, or as two doses: first packet in evening, second and third packets next morning. Route: oral. Frequency: single or split dose for colonoscopy preparation.

Terminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment (up to 20 hours).
Not applicable as intact drug; component electrolytes have variable half-lives: sulfate ~12-24 hours; potassium and magnesium are actively regulated with redistribution half-lives of minutes to hours.
Primarily renal (30-50% unchanged) and biliary/fecal (50-70% as inactive metabolites).
Primarily renal: sulfate ions are excreted unchanged in urine; minimal biliary/fecal elimination (<5%).
