What is the mechanism of action of desmopressin?
By mimicking the actions of endogenous ADH, desmopressin acts as a selective agonist of V2 receptors expressed in the renal collecting duct (CD) to increase water re-absorption and reduce urine production.
What is desmopressin acetate DDAVP used for?
DDAVP (desmopressin acetate) is an antidiuretic and antihemorrhagic drug used to treat bed-wetting, central cranial diabetes insipidus, and increased thirst and urination caused by head surgery or head trauma. DDAVP is also used to treat bleeding due to platelet dysfunction. DDAVP is available in generic form.
What is the function of desmopressin?
Desmopressin is used to control the symptoms of a certain type of diabetes insipidus (‘water diabetes’; condition in which the body produces an abnormally large amount of urine).
What is the effect of DDAVP?
Desmopressin (DDAVP®) is used to help stop bleeding in patients with von Willebrand’s disease or mild hemophilia A. DDAVP causes the release of von Willebrand’s antigen from the platelets and the cells that line the blood vessels where it is stored.
Does DDAVP increase platelets?
We show that in vivo DDAVP selectively and markedly enhances the ability to form procoagulant platelets and increases platelet-dependent thrombin generation by enhancing Na+/Ca2+ mobilization.
How does DDAVP work for bleeding?
DDAVP increases the amount of factor VIII and von Willebrand factor circulating in your blood by around three to five times your normal level. This effect lasts for 12 to 24 hours. The increase is usually enough to control minor bleeding and to avoid bleeding from minor operations, including dentistry.
What does DDAVP do to platelets?
DDAVP is the drug of choice for mild hemophilia A and von Willebrand disease and (by unclear mechanisms) for platelet function disorders. In vivo DDAVP selectively and markedly enhances the ability to form procoagulant platelets by enhancing intracellular Na+ and Ca2+ fluxes.
What is vasopressin used for?
Vasopressin is used to treat diabetes insipidus, which is caused by a lack of a naturally occurring pituitary hormone in the body. Vasopressin is also used to treat or prevent certain conditions of the stomach after surgery or during abdominal x-rays.
When do we use DDAVP?
For the treatment of bedwetting, take this medication by mouth, usually once a day at bedtime. Children should limit the fluids they drink after dinner, especially 1 hour before the desmopressin dose until the next morning, or at least 8 hours after the dose.
When do you give DDAVP?
How does desmopressin work on platelets?
Increases the density of platelet surface glycoprotein receptors. Enhances the ability to form procoagulant platelets and increases platelet-dependent thrombin generation by enhancing Na+/Ca2+ mobilization. Thus, increases platelet aggregation. Also, increase activity of tissue plasminogen activator antigen.
What is the expected action of vasopressin?
In patients with vasodilatory shock vasopressin in therapeutic doses increases systemic vascular resistance and mean arterial blood pressure and reduces the dose requirements for norepinephrine. Vasopressin tends to decrease heart rate and cardiac output.
What is the purpose for desmopressin acetate used?
Desmopressin acetate (DDAVP, Stimate, Minirin) is a medication prescribed for the management of thirst and urination following head trauma or surgery involving the pituitary gland, and the treatment of diabetes insipidus .
What conditions does desmopressin acetate treat?
Desmopressin Acetate (DDAVP) DDAVP is a drug to treat children with bed-wetting. Although DDAVP does not cure the condition, it does help treat the symptoms while the child is on the drug. Numerous studies report reduction in the number of wet nights.
Where to buy desmopressin?
