Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Laxilose (lactulose) is a synthetic disaccharide that is not absorbed in the small intestine. In the colon, it is metabolized by bacteria to short-chain fatty acids (e.g., lactic, acetic, formic acids), which osmotically draw water into the bowel lumen, stimulating peristalsis and softening stools. Additionally, in hepatic encephalopathy, colonic acidification traps ammonia (NH3) as ammonium (NH4+), reducing systemic ammonia absorption.
Osmotic laxative; induces bowel cleansing by retaining water in the intestinal lumen via osmotic effects, increasing intraluminal pressure and stimulating peristalsis.
10-20 g (15-30 mL) orally once daily; may increase to 40 g (60 mL) daily in divided doses.
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 2.5-4 hours in patients with normal renal function; prolonged to up to 20 hours in severe 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 excretion, with approximately 40% of the dose recovered as unchanged drug in urine; biliary/fecal excretion accounts for the remainder, including metabolites.
Primarily renal: sulfate ions are excreted unchanged in urine; minimal biliary/fecal elimination (<5%).
