Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lactulose is a synthetic disaccharide that is not absorbed from the gastrointestinal tract. It is metabolized by colonic bacteria to form low molecular weight organic acids, which lower the colonic pH and increase osmotic pressure, resulting in increased stool volume and laxative effect. In hepatic encephalopathy, the acidification of the colon inhibits the growth of ammonia-producing bacteria and promotes the conversion of ammonia to ammonium ion, which is trapped in the colon and excreted, thereby reducing systemic ammonia levels.
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.
15-45 mL orally once daily, titrated to produce 2-3 soft stools per day. Maximum 60 mL 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 2.1 hours in normal renal function; prolonged to up to 6 hours in renal impairment.
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 (95% unchanged by glomerular filtration); biliary/fecal less than 5%.
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.
