Desmopressin acetate, the acetate salt of desmopressin (also known as DDAVP), is a synthetic octapeptide and an analogue of the human antidiuretic hormone arginine vasopressin. Compare with vasopressin, Desmopressin has improved pharmacokinetics such as prolonged half life and better pharmacodynamics such as higher selectivity for the V2 membrane receptor. Vasopressin is a hormone that reduces the production of urine and desmopressin is a synthetic version for vasopressin. The antidiuretic properties of desmopressin have led to its use in polyuric conditions including primary nocturnal enuresis, nocturia, and diabetes insipidus. Desmopressin works by limiting the amount of water eliminated in the urine. Desmopressin binds to V2 receptors in renal collecting ducts, increasing water reabsorption. It also stimulates release of von Willebrand factor from endothelial cells by acting on the V2 receptor. Desmopressin is most frequently prescribed for treatment of diabetes insipidus or nocturnal enuresis.

| Additional Infomation |
Desmopressin Acetate is an analogue of the hormone vasopressin with antidiuretic and antihemorrhagic properties. Desmopressin acetate has selective affinity for the V2 receptor and acts on the distal kidney tubule by increasing the cellular permeability thereby stimulating water reabsorption. This antidiuretic agent is used in the treatment of central diabetes insipidus. An unrelated action of desmopressin acetate is to increases circulating factor VIII and is used in patients with haemophilia and von Willebrand's disease.
A synthetic analog of the pituitary hormone, ARGININE VASOPRESSIN. Its action is mediated by the VASOPRESSIN receptor V2. It has prolonged antidiuretic activity, but little pressor effects. It also modulates levels of circulating FACTOR VIII and VON WILLEBRAND FACTOR. |

| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 0.8855 mL | 4.4276 mL | 8.8553 mL | |
| 5 mM | 0.1771 mL | 0.8855 mL | 1.7711 mL | |
| 10 mM | 0.0886 mL | 0.4428 mL | 0.8855 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
