Desmopressin

FDA-approved selective V2 receptor agonistEstablished

Desmopressin is an FDA-approved selective V2 receptor agonist in the Vasopressin Receptor Agonist class. Two structural modifications to vasopressin — deamination at position 1 and substitution of D-arginine at position 8 — give desmopressin strong selectivity for the V2 receptor over V1a, so antidiuretic activity is retained while pressor activity is largely lost.

How it works

Each step shows whether the sources Peptide Library has reviewed include that kind of research. Counts are reviewed sources, not every study ever published. Reviews and programme summaries that describe human use are shown as "reported", not as trials, and registered trials without published results are listed but not counted. A higher step means research has progressed further; it does not mean a compound works better or is safer. Compounds whose evidence has not been reviewed yet show "Not reviewed" instead of a guess.

Peptide Library's Desmopressin profile summarises 5 cited studies listed in the Science section, the compound's regulatory status, and research-protocol parameters reported for it. It is a research reference, not medical advice.

Desmopressin dosage evidence

Desmopressin has FDA-approved human dosages that differ by form and use. DDAVP tablets for central diabetes insipidus start at 0.05 mg twice daily, with most patients in the label's trials using 0.1–0.8 mg a day in divided doses; for bedwetting in children aged 6 and over they start at 0.2 mg at bedtime. DDAVP injection is 2–4 mcg a day for diabetes insipidus, and 0.3 mcg/kg intravenously (up to 20 mcg) in hemophilia A and type 1 von Willebrand disease.

Where sources disagree

  • Oral doses are in milligrams and injected doses in micrograms because very little of an oral dose is absorbed. Figures from one form do not transfer to another.
  • The DDAVP injection label carries a boxed warning that desmopressin can cause hyponatremia. The labels require fluid restriction and serum sodium checks during treatment.

Science

Mechanism of Action

Two structural modifications to vasopressin — deamination at position 1 and substitution of D-arginine at position 8 — give desmopressin strong selectivity for the V2 receptor over V1a, so antidiuretic activity is retained while pressor activity is largely lost. V2 stimulation promotes renal water reabsorption, and separately triggers release of von Willebrand factor and factor VIII from vascular endothelial storage sites.

Storage & stability

This compound is not supplied as a powder to be mixed, so the freeze-dried powder and reconstitution handling described for research peptides does not apply. Storage conditions are product-specific: follow the label or packaging of the product itself.

Desmopressin: frequently asked questions

What is Desmopressin?

Synthetic vasopressin analog approved for central diabetes insipidus, primary nocturnal enuresis, nocturia, and for raising factor VIII and von Willebrand factor in mild haemophilia A and type 1 von Willebrand disease.

How does Desmopressin work?

Two structural modifications to vasopressin — deamination at position 1 and substitution of D-arginine at position 8 — give desmopressin strong selectivity for the V2 receptor over V1a, so antidiuretic activity is retained while pressor activity is largely lost. V2 stimulation promotes renal water reabsorption, and separately triggers release of von Willebrand factor and factor VIII from vascular endothelial storage sites.

Is Desmopressin FDA approved?

Yes. Desmopressin is approved by the FDA, and approved products are prescription medicines. Approval is always for specific indications studied in clinical trials, so an approved status does not mean the compound is approved for every use it is discussed for. Research-chemical material sold under the same name is not the approved product.

What peptides are similar to Desmopressin?

Compounds most often compared with Desmopressin include Vasopressin, Terlipressin, Angiotensin II and Cetrorelix. They are grouped by shared mechanism or research area rather than by equivalence, and their regulatory status and evidence base differ.
