Nocutil Melt (Desmopressin)

Desmopressin, the active ingredient in Nocutil Melt, is a vasopressin analog presented as a sublingual melt for sublingual use. It is used to reduce urine output in central diabetes insipidus, control nocturnal enuresis, and increase clotting factor levels in hemophilia A and von Willebrand disease. It is approved for use in the European Union.

GNH USA supplies Nocutil Melt as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, adhering to stringent quality standards and providing reliable logistics for global distribution.

Desmopressin acts on the vasopressin V2 receptor pathway to manage conditions related to water balance and coagulation.

- Nocturnal enuresis: reduces nighttime urine production, helping achieve dry nights. - Central diabetes insipidus: increases renal water reabsorption to control polyuria and polydipsia. - Hemophilia A: raises plasma factor VIII levels to improve clot formation. - Von Willebrand disease: enhances release of von Willebrand factor, supporting hemostasis.

Desmopressin may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Headache - Nausea - Nasal congestion - Mild hyponatremia

Serious or Rare Side Effects: - Severe hyponatremia leading to seizures or coma - Water intoxication with cerebral edema - Thromboembolic events such as deep‑vein thrombosis - Anaphylactic or severe allergic reactions

Before prescribing Nocutil Melt, clinicians should consider several precautionary measures to minimise risk.

- Assess serum sodium: check baseline sodium levels and monitor during therapy. - Monitor fluid intake: advise patients to limit excessive water consumption. - Avoid concomitant antidiuretic agents: concurrent use with vasopressin analogs may exacerbate hyponatremia. - Use caution in renal impairment: adjust therapy in patients with reduced kidney function. - Contraindicated in uncontrolled hyponatremia: do not use if serum sodium is already low. - Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.

Desmopressin can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - Other ADH analogues (e.g., vasopressin): may cause profound hyponatremia. - Loop diuretics: can reduce antidiuretic effect and destabilise fluid balance. - NSAIDs: may potentiate water retention and hyponatremia risk. - Carbamazepine: increases risk of severe hyponatremia.

Moderate Interactions (Monitor Closely): - Selective serotonin reuptake inhibitors (SSRIs): may enhance hyponatremia. - Anticonvulsants such as oxcarbazepine: can affect sodium homeostasis. - Alcohol: may increase water retention and hyponatremia potential.
