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.
Sorbitol is a sugar alcohol that acts as an osmotic diuretic. When administered intravenously, it increases plasma osmolality, drawing water from extravascular spaces into the intravascular compartment, thereby reducing intracranial pressure and cerebral edema. It is also used as a hyperosmotic laxative via oral administration, drawing water into the colon to stimulate bowel movements.
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.
30 mL of 3% solution (0.9 g) administered intravenously over 30-60 minutes, typically as a single dose.

Terminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment (up to 20 hours).
Terminal elimination half-life is approximately 1.5-2 hours in patients with normal renal function; prolonged in renal impairment (up to 6 hours in anuria).
Primarily renal (30-50% unchanged) and biliary/fecal (50-70% as inactive metabolites).
Sorbitol is primarily excreted renally as metabolites (fructose and glucose) and unchanged drug; approximately 50-70% is recovered in urine over 24 hours, with less than 10% eliminated in feces.
