Hepatic Encephalopathy Understanding and Treatment Algorithm

Hepatic Encephalopathy Overview and Diagnosis

Hepatic encephalopathy (HE) is a diagnosis of exclusion characterized by a spectrum of neuropsychiatric disturbances resulting from the accumulation of neurotoxins in patients with liver dysfunction or portosystemic shunting. It differs in presentation and pathophysiology between chronic liver disease, acute liver failure, and acute-on-chronic liver failure, with mechanisms extending beyond hyperammonemia to include systemic inflammation, gut dysbiosis, altered neurotransmission, oxidative stress, manganese deposition, and other toxins. HE is broadly classified into covert (minimal HE and West Haven grade 1) and overt (grades 2-4) forms, representing a continuum of severity; overt HE is defined by disorientation or asterixis, while minimal HE, affecting up to 80% of patients with cirrhosis, requires specialized testing for detection.

Clinical manifestations range from subtle cognitive and behavioral changes, sleep-wake disturbances, anxiety, irritability, poor concentration, musty breath (fetor hepaticus), and impaired fine motor skills to confusion, lethargy, incoherent speech, tremors, myoclonus, asterixis, profound personality changes, seizures, and coma, with severe cases in cirrhosis carrying a one-year mortality exceeding 50%. Ammonia, produced by intestinal bacteria and peripheral tissues, accumulates due to impaired hepatic metabolism and portal hypertension-related shunting, crosses the blood-brain barrier, and is converted to glutamine in astrocytes, causing osmotic swelling, neuroinflammation, and disrupted synaptic transmission; reduced muscle mass and branched-chain amino acids further impair ammonia detoxification. HE may arise from liver disease or shunts such as transjugular intrahepatic portosystemic shunt (TIPS) and spontaneous shunts, as well as from acute liver failure due to viral hepatitis, hepatotoxins (eg, acetaminophen), or ischemia, and chronic cirrhosis from alcohol use, viral hepatitis B or C, nonalcoholic fatty liver disease, hemochromatosis, Wilson disease, or alpha-1 antitrypsin deficiency; it can also occur without intrinsic liver disease in congenital or extrahepatic portosystemic shunts. In cirrhosis, common precipitants include gastrointestinal bleeding, constipation, infections, dehydration, electrolyte imbalance, alcohol use, sedative medications, renal dysfunction, and azotemia, while 30%-50% of patients undergoing TIPS may develop HE, though risk is reduced with smaller stents and careful selection; progressive spontaneous shunting further worsens portal flow and hepatic failure over time.

Hepatic encephalopathy (HE) is broadly classified into covert and overt forms, representing a continuum of disease severity. Covert HE includes minimal HE and West Haven grade 1, while overt HE encompasses grades 2 through 4. The West Haven criteria provide a semi-quantitative assessment of mental status based on impairments in consciousness, behavior, autonomy, and intellectual function, ranging from grade 1 (mild inattention, anxiety or euphoria, and subtle cognitive deficits) to grade 2 (lethargy, mild disorientation, and inappropriate behavior), grade 3 (marked confusion, gross disorientation, and somnolence responsive to verbal stimuli), and grade 4 (coma). Alternatively, the World Health Congress of Gastroenterology classifies HE by etiology into type A (acute liver failure, often with cerebral edema), type B (portosystemic shunting without intrinsic liver disease), and type C (cirrhosis-related, further subdivided into episodic, persistent, and minimal forms). Minimal HE lacks overt clinical signs but presents with subtle cognitive impairments detectable through neuropsychological testing; it significantly affects quality of life, work performance, and driving safety. Diagnostic evaluation relies on psychometric tools such as the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and the PSE-Syndrome test, which assess multiple cognitive domains and offer more comprehensive and reliable detection than single-function tests.

Hepatic encephalopathy (HE) is a diagnosis of exclusion requiring initial assessment of airway and vital signs, followed by detailed history and examination to identify triggers and rule out mimics such as alcohol withdrawal. Laboratory evaluation includes arterial blood gas, blood glucose, liver function tests, coagulation profile, renal function, and electrolytes, with attention to infection markers when indicated. Although ammonia levels are often elevated, they are not diagnostic and correlate poorly with severity, though normal levels have high negative predictive value. Psychometric tests such as the Number Connection Test and Critical Flicker Frequency are sensitive for minimal HE, while EEG may show nonspecific changes and help exclude seizures. CT or MRI is used to rule out structural causes; imaging findings like cerebral edema or basal ganglia changes may occur but are not specific for HE.

Current Hepatic Encephalopathy Treatment Landscape

Management of hepatic encephalopathy (HE) involves supportive care, correction of precipitating factors, and ammonia-lowering therapy. Patients require adequate nutrition without protein restriction (35-40 kcal/kg/day; 1.2-1.5 g/kg/day protein), proper hydration, electrolyte correction, and a safe environment while avoiding sedatives. Triggers such as constipation, infections, electrolyte imbalance, hypovolemia, renal dysfunction, and sedative use must be promptly treated. Ammonia levels guide neither diagnosis nor therapy alone; treatment is symptom-driven. First-line therapy is lactulose (titrated to 2-3 soft stools daily), with rifaximin added for recurrence or inadequate response; lactitol and L-ornithine-L-aspartate are alternatives. Refractory cases due to portosystemic shunts may require shunt occlusion procedures, while liver transplantation is indicated in advanced cirrhosis and can reverse cognitive impairment. Long-term prevention includes maintenance lactulose +- rifaximin and management of sarcopenia with nutrition and exercise.

Approved Therapies for Hepatic Encephalopathy

Xifaxan (Rifaximin): BAUSCH Health

Xifaxan(R) (rifaximin) 550 mg tablets, developed and marketed by Salix Pharmaceuticals (a subsidiary of Valeant Pharmaceuticals whose company name changes to BAUSCH Health), are indicated to reduce the risk of recurrent overt hepatic encephalopathy in adults aged =18 years. Rifaximin is a non-absorbed, broad-spectrum, gastrointestinal-selective antibiotic derived from rifamycin that targets both Gram-positive and Gram-negative, aerobic and anaerobic ammonia-producing bacteria, thereby lowering systemic ammonia levels implicated in hepatic encephalopathy. Unlike systemic antibiotics, rifaximin remains within the gastrointestinal tract without significant absorption and exerts its effect by binding to the B-subunit of bacterial DNA-dependent RNA polymerase, inhibiting transcription by blocking the translocation step following the formation of the first phosphodiester bond.

Hepatic Encephalopathy Pipeline Analysis

VE303: Vedanta Biosciences

VE303 is an orally administered, wholly owned defined bacterial consortium composed of eight live commensal strains developed to prevent recurrent Clostridioides difficile infection (rCDI). It is formulated as a standardized oral pharmaceutical product manufactured from pure clonal cell banks to ensure consistent quality. The selected strains function synergistically to reduce recurrence by competing with C. difficile for growth substrates and producing secondary bile acids that suppress its proliferation, as well as short-chain fatty acids that enhance gut barrier integrity and mitigate intestinal inflammation. Currently, the drug is in Phase II stage of its development for the treatment of Hepatic Encephalopathy.

The data were presented during an oral session at the European Association for the Study of the Liver (EASL) Congress 2025, held in Amsterdam, the Netherlands from 7-10 May 2025.

Hepatic Encephalopathy Market Outlook

Hepatic encephalopathy is a diagnosis of exclusion marked by neuropsychiatric abnormalities from liver dysfunction. It arises from liver insufficiency or portosystemic shunting and involves a multifactorial etiology, including hyperammonemia, systemic inflammation, gut dysbiosis, neurotransmitter imbalances, and neurotoxins like manganese. Current management of hepatic encephalopathy (HE) centers on reducing intestinal ammonia production and absorption. Non-absorbable disaccharides such as lactulose and lactitol remain the cornerstone of therapy, used for treating acute episodes as well as for primary and secondary prevention; lactitol demonstrates comparable efficacy to lactulose and may offer improved tolerability in some patients. Antibiotics aimed at colonic decontamination, including neomycin, metronidazole, and vancomycin, further decrease ammonia-producing gut bacteria and may also mitigate inflammation and endotoxemia. Second-line and emerging therapies include polyethylene glycol 3350-electrolyte solution, ammonia scavengers, branched-chain amino acids fecal microbiota transplantation, and L-ornithine L-aspartate. Currently, only one drug is approved for Hepatic Encephalopathy treatment i.e. XIFAXAN (Rifaximin) which is an oral small molecule.

Xifaxan (rifaximin) 550 mg, marketed by Salix Pharmaceuticals, is approved for reducing the recurrence of overt hepatic encephalopathy in adults. It is an oral, small-molecule, DNA-directed RNA polymerase inhibitor and a non-absorbed, gut-selective, broad-spectrum antibiotic that targets ammonia-producing Gram-positive and Gram-negative bacteria. As a semi-synthetic rifamycin derivative, rifaximin acts locally in the intestine by binding to the B-subunit of bacterial RNA polymerase, thereby suppressing bacterial RNA synthesis.

Companies, including Vedanta Biosciences, Yaqrit Discovery Ltd and others, are investigating potential drug candidates that can significantly change the market landscape during the forecast period. Approaches include microbiome modulation (VE303), Ammonia scavenging agents (YAQ007), and and others.

Overall, the launch of therapies, improved diagnosis, and rising disease awareness are expected to drive steady growth in the 7MM Hepatic Encephalopathy market from 2022-2036, with strong commercial implications for both marketed products and emerging pipelines.

  • In 2025, the United States held the largest market share for Hepatic Encephalopathy among the 7MM, accounting for approximately 60% of the total market.
  • In 2025, Rifaximin in combination with Lactulose led the US Hepatic Encephalopathy treatment market and is projected to retain its position as the dominant market leader through 2036.

Drug Class/Insights into Leading Emerging and Marketed Therapies in HEPATIC ENCEPHALOPATHY (2022-2036 Forecast)

The Hepatic Encephalopathy market comprises of different mechanism class, including microbiome modulator, ammonia-scavenging, and others, each designed to target distinct pathways underlying disease pathophysiology.

  • Microbiome Modulator: Microbiome modulation involves deliberately altering the composition and activity of microbial communities to improve health and treat disease. It works by restoring microbial balance, suppressing harmful pathogens, producing beneficial metabolites (like short-chain fatty acids and secondary bile acids), enhancing gut barrier integrity, regulating immune responses, and influencing distant organs via the gut-brain and gut-liver axes. Approaches include dietary interventions, probiotics, prebiotics, fecal microbiota transplantation, and microbiome engineering, with applications in gastrointestinal disorders, metabolic syndrome, neurological conditions, and infectious diseases.
  • Ammonia scavenging agents: In hepatic encephalopathy, impaired liver function and portosystemic shunting reduce ammonia detoxification, leading to neurotoxicity. Ammonia scavengers lower systemic ammonia by providing alternative pathways: compounds like sodium benzoate or phenylacetate conjugate with amino acids (glycine or glutamine) to form water-soluble derivatives (hippurate, phenylacetylglutamine) that are excreted in urine, while L-ornithine L-aspartate stimulates residual urea cycle and glutamine synthesis in liver and muscle, enhancing ammonia elimination. Examples include oral small molecule such as YAQ-007.

Hepatic Encephalopathy Drug Uptake

Market Access and Reimbursement of Approved therapies in Hepatic Encephalopathy

The report further provides detailed insights on the country-wise accessibility and reimbursement scenarios, cost-effectiveness scenario of approved therapies, programs making accessibility easier and out-of-pocket costs more affordable, insights on patients insured under federal or state government prescription drug programs, etc.

The United States

Rifaximin (XIFAXAN)

Prior authorization (PA) for XIFAXAN requires submission of accurate clinical and insurance information to secure coverage. To prevent denials, clinicians should ensure correct ICD-10 coding and align prescriptions with approved dosing (550 mg three times daily for 14 days for IBS-D; 550 mg twice daily for OHE). If denied, the request should be reviewed, completed with any missing details, and resubmitted with appropriate clinical documentation; if coverage appears excluded, benefits should be reverified and reconsideration requested, as most commercially insured and Medicare patients have coverage.

The Copay Savings Card helps eligible commercially insured U.S. patients reduce out-of-pocket costs for XIFAXAN, with many paying USD 10 or less per prescription, and some as low as USD 0, subject to benefit limits. The program is available only to patients with commercial insurance coverage for XIFAXAN and excludes those insured through federal or state healthcare programs (e.g., Medicare, Medicaid, TRICARE, VA, or other government-funded plans), as well as cash-paying patients. The card is nontransferable, not insurance, cannot be combined with other offers, holds no cash value, and is redeemable only at participating U.S. retail pharmacies; by using it, patients confirm eligibility and agree to the program's terms.

Reimbursement is a crucial factor that affects the drug's access to the market. Often, the decision to reimburse comes down to the price of the drug relative to the benefit it produces in treated patients. To reduce the healthcare burden of these high-cost therapies, many payment models are being considered by payers and other industry insiders.
