Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ammonia scavenger; lactulose is metabolized by colonic bacteria to organic acids, acidifying the colon, which converts NH3 to NH4+ and promotes ammonia excretion. Lactulose also reduces colonic transit time and bacterial production of ammonia.
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: 3.33 g (30 mL) 3 times daily. Rectal: 200 mL of 30% solution as retention enema, 3 times daily. Intravenous: 30 g as a single dose via intra-abdominal instillation.
30 mL of 3% solution (0.9 g) administered intravenously over 30-60 minutes, typically as a single dose.

Terminal elimination half-life is 6-12 hours in patients with normal hepatic function; prolonged in hepatic encephalopathy due to altered clearance (up to 24 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 (approximately 70-80%) as unchanged drug; minor biliary/fecal elimination (20-30%).
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.
