LAXILOSE vs TRILYTE
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.
TRILYTE (polyethylene glycol 3350, sodium sulfate, sodium chloride, potassium chloride, sodium ascorbate, ascorbic acid) is an osmotic laxative. The active components induce diarrhea by osmotically drawing water into the gastrointestinal lumen, thereby increasing stool volume and stimulating peristalsis. Sodium ascorbate and ascorbic acid enhance the osmotic effect.
10-20 g (15-30 mL) orally once daily; may increase to 40 g (60 mL) daily in divided doses.
Adults: 1 liter (L) orally every 10-15 minutes until 4 L total consumed; complete ingestion within 4 hours.

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; non-absorbed, acts locally in GI tract
Primarily renal excretion, with approximately 40% of the dose recovered as unchanged drug in urine; biliary/fecal excretion accounts for the remainder, including metabolites.
Renal excretion of intact electrolyte ions; negligible drug excretion
