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.
Linaclotid
Linaclotide activates the guanylate cyclase-C receptor on the luminal surface of the intestinal epithelium. This raises cyclic GMP (cGMP), increases secretion of chloride and bicarbonate into the lumen, raises stool fluid content and accelerates transit; pain signaling is also modulated.

Frequently asked questions
- What is the difference between Enfuvirtid and Linaclotid?
- Enfuvirtid is classified as "Research other", while Linaclotid 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. Linaclotid: Linaclotide is a 14-amino-acid peptide and guanylate cyclase-C (GC-C) agonist. It is approved for irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Enfuvirtid or Linaclotid?
- The highest available evidence level is "Human RCT" for Enfuvirtid and "Human RCT" for Linaclotid. 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 Linaclotid in Germany and the United States?
- Germany: Enfuvirtid — Prescription, Linaclotid — Prescription. United States: Enfuvirtid — Prescription, Linaclotid — Prescription. These are factual summaries with source and review date on the individual pages.
