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.
Vasopressin
Vasopressin binds V1 receptors (vasoconstriction, raising vascular resistance) and V2 receptors (renal water reabsorption via aquaporin channels). This raises blood pressure and acts antidiuretically. Desmopressin is the V2-selective synthetic analog.

Frequently asked questions
- What is the difference between Enfuvirtid and Vasopressin?
- Enfuvirtid is classified as "Research other", while Vasopressin 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. Vasopressin: Vasopressin (arginine vasopressin, antidiuretic hormone/ADH) is a cyclic nonapeptide hormone that regulates water balance and vascular tone. As Vasostrict it is approved to raise blood pressure in vasodilatory shock. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Enfuvirtid or Vasopressin?
- The highest available evidence level is "Human RCT" for Enfuvirtid and "Human RCT" for Vasopressin. 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 Vasopressin in Germany and the United States?
- Germany: Enfuvirtid — Prescription, Vasopressin — Prescription. United States: Enfuvirtid — Prescription, Vasopressin — Prescription. These are factual summaries with source and review date on the individual pages.
