Nordurine (Desmopressin Acetate)

Desmopressin Acetate, the active ingredient in Nordurine, is a vasopressin analog presented as an oral tablet for oral use. It is employed to manage central diabetes insipidus, nocturnal enuresis in children and adults, and certain bleeding disorders such as hemophilia A and von Willebrand disease.

GNH USA supplies Nordurine as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU quality standards and provides regulatory‑approved batches for global distribution.

Desmopressin acetate acts on the antidiuretic hormone pathway to control water balance and hemostasis.

Central diabetes insipidus: reduces excessive urine output by enhancing renal water reabsorption. Nocturnal enuresis: decreases nighttime bedwetting episodes by concentrating urine. Hemophilia A and von Willebrand disease: raises plasma levels of factor VIII and von Willebrand factor to improve clotting.

Desmopressin acetate may be associated with a range of adverse reactions, most of which are mild and dose‑related.

Common Side Effects: - Headache: mild to moderate headache reported. - Nausea: occasional upset stomach. - Mild hyponatremia: slight reduction in blood sodium levels.

Serious or Rare Side Effects: - Severe hyponatremia: can lead to seizures or coma. - Water intoxication: excessive fluid retention causing edema. - Allergic reaction: rash, swelling, or anaphylaxis in rare cases.

When prescribing desmopressin acetate, clinicians should consider several safety measures.

Renal function: assess kidney function before initiating therapy. Fluid intake: limit excessive water consumption to reduce hyponatremia risk. Electrolytes: monitor serum sodium regularly during treatment. Cardiovascular disease: use caution in patients with heart failure or hypertension. Concomitant drugs: avoid simultaneous use of other antidiuretic agents. Store at ambient temperature: keep below 25 °C, retain in original container, protect from moisture.

Desmopressin acetate can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Concomitant use of other vasopressin analogues: additive antidiuretic effect may cause severe hyponatremia. - Strong CYP3A4 inhibitors: may increase desmopressin exposure (e.g., ketoconazole).

Moderate Interactions (Monitor Closely): - Diuretics (especially thiazides): can potentiate water retention and hyponatremia. - NSAIDs: may reduce renal prostaglandin synthesis, enhancing antidiuretic effect. - Anticoagulants (e.g., warfarin): monitor clotting parameters when using for bleeding disorders.
