Terlipressin: From Variceal Bleeding and Hepatorenal Syndrome to Open-Angle Glaucoma
One-Sentence Summary
Terlipressin is a synthetic vasopressin analogue historically used to control acute variceal bleeding and hepatorenal syndrome in patients with liver cirrhosis. The TxGNN model predicts it may be effective for Open-Angle Glaucoma, but this direction is currently supported by zero clinical trials and zero published literature — it is a pure knowledge-graph association without pharmacological or clinical backing.

Why is This Prediction Reasonable?
Detailed mechanism of action data is not available in this evidence pack (data gap, high severity). Based on established clinical knowledge, terlipressin is a V1 vasopressin-receptor agonist whose therapeutic value comes from potent splanchnic vasoconstriction, which is why it is used for variceal hemorrhage and hepatorenal syndrome — conditions driven by portal hypertension and systemic vasodilation in cirrhosis.
There is no clinical or mechanistic evidence connecting this V1-agonist vasoconstrictive action to intraocular pressure reduction in open-angle glaucoma. The high TxGNN score reflects a purely statistical knowledge-graph association rather than established pharmacology. If anything, systemic vasoconstrictors could theoretically raise rather than lower intraocular pressure, which runs counter to the therapeutic goal in glaucoma. As the evidence pack’s own rationale notes, this prediction has “no pharmacological plausibility” supporting the connection.
Given the complete absence of clinical trials, literature, or mechanistic rationale, this candidate should be treated as a low-confidence model artifact rather than a genuine repurposing signal at this time.

Conclusion and Next Steps
Decision: Hold
Rationale: The TxGNN score is high, but there are no clinical trials, no supporting literature, and no mechanistic rationale linking terlipressin’s V1-agonist vasoconstrictive action to intraocular pressure reduction — this is an L5, S0-stage prediction with no evidentiary support. Note also that other predictions for this drug (e.g., rank 3, pulmonary hypertension in the context of cirrhosis, L3/S1 with cohort-level literature) show meaningfully stronger evidence and may warrant separate evaluation.
To proceed, the following is needed:
- Confirmed mechanism of action data (DG002, currently a data gap)
- TFDA/CDSCO label warnings and contraindications (DG001, blocking gap for safety review)
- Preclinical or mechanistic studies on vasopressin agonists and intraocular pressure
- Any real-world or case-level evidence before advancing past S0
