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.
Osmotic laxative; induces bowel cleansing by retaining water in the intestinal lumen via osmotic effects, increasing intraluminal pressure and stimulating peristalsis.
15-45 mL orally once daily, titrated to produce 2-3 soft stools per day. Maximum 60 mL 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 2.1 hours in normal renal function; prolonged to up to 6 hours in renal impairment.
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 (95% unchanged by glomerular filtration); biliary/fecal less than 5%.
Primarily renal: sulfate ions are excreted unchanged in urine; minimal biliary/fecal elimination (<5%).
