From the Guidelines

For the management of hepatic encephalopathy, the most effective pharmacological option is not Aminoleban IV, but rather lactulose, which should be administered orally at a dose of 20–30 g, 3–4 times per day, with the goal of achieving two to three soft stools per day 1. The provided evidence does not support the use of Aminoleban IV for hepatic encephalopathy, instead, it recommends the following pharmacological options:

  • Non-absorbable disaccharides, such as lactulose, which should be administered orally until the patient is having at least 2 bowel movements a day, and then titrated to achieve two to three soft stools per day 1
  • Rifaximin, at a dose of 400 mg three times/day or 550 mg twice/day 1
  • Oral BCAA, at a dose of 0.25 g/kg/day 1
  • Intravenous LOLA, at a dose of 30 g/day 1
  • Albumin, at a dose of 1.5 g/kg/day until clinical improvement or for 10 days, maximum 1 Key considerations for the management of hepatic encephalopathy include:
  • Monitoring ammonia levels, mental status, and electrolytes during treatment
  • Ensuring adequate caloric intake alongside treatment, as protein restriction alone may worsen nutritional status
  • Adjusting dosing for patients with renal impairment
  • Discontinuing treatment if significant adverse reactions occur, including hypersensitivity reactions or worsening encephalopathy.
