ENULOSE vs TRILYTE
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.
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.
15-45 mL orally once daily, titrated to produce 2-3 soft stools per day. Maximum 60 mL per day.
Adults: 1 liter (L) orally every 10-15 minutes until 4 L total consumed; complete ingestion within 4 hours.
