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.

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.

Regulatory & research status

Desmopressin is an FDA-approved product for specific labelled indications. Approval does not extend to the research contexts described on this page, and approved products are prescription medicines.

Storage & stability

Lyophilized (freeze-dried) peptide powder is far more stable than the reconstituted solution. Keep sealed vials cold, dry and away from light; long-term storage is typically frozen, with short-term refrigeration for vials in use.

Once reconstituted in bacteriostatic water, keep the solution refrigerated, avoid repeated freeze–thaw cycles and agitation, and label the vial with the reconstitution date and concentration. Discard any solution that turns cloudy or shows particulates.

Degradation rates differ by sequence: peptides containing methionine, cysteine, asparagine or glutamine are more prone to oxidation and deamidation, so shelf life after reconstitution is compound-specific rather than universal.

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.
