Mechanism of action
Enfuvirtid
Enfuvirtide binds the first heptad-repeat region (HR1) of the gp41 subunit of the HIV envelope protein. This prevents the conformational change required for fusion of the viral and cell membranes — the virus cannot enter the cell.
Terlipressin
Terlipressin is slowly converted in the body to lysine-vasopressin by cleavage of the three N-terminal glycyl residues (reservoir effect) and activates V1 receptors. The splanchnic vasoconstriction improves renal perfusion in hepatorenal syndrome.

Frequently asked questions
- What is the difference between Enfuvirtid and Terlipressin?
- Enfuvirtid is classified as "Research other", while Terlipressin is classified as "Research other". Enfuvirtid: Enfuvirtide is a synthetic 36-amino-acid peptide and the first HIV-1 fusion inhibitor. It binds the HR1 region of the viral envelope protein gp41, blocking viral entry into the cell. Approved for treatment-experienced HIV patients. Terlipressin: Terlipressin is a 12-amino-acid vasopressin analog and prodrug of lysine-vasopressin. As a V1 receptor agonist it is vasoconstrictive and is approved for hepatorenal syndrome (FDA 2022, Terlivaz). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Enfuvirtid or Terlipressin?
- The highest available evidence level is "Human RCT" for Enfuvirtid and "Human RCT" for Terlipressin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Enfuvirtid and Terlipressin in Germany and the United States?
- Germany: Enfuvirtid — Prescription, Terlipressin — Prescription. United States: Enfuvirtid — Prescription, Terlipressin — Prescription. These are factual summaries with source and review date on the individual pages.
