Nocdurna (Desmopressin)

Desmopressin, the active ingredient in Nocdurna, is a vasopressin analog presented as a 0.1 mg sublingual tablet for sublingual use. It acts as an antidiuretic to reduce excessive nighttime urine production in adult patients with nocturnal polyuria.

GNH USA supplies Nocdurna as a licensed, GDP‑compliant international pharmaceutical supplier, providing the product to hospitals, pharmacies and clinics worldwide under strict quality‑assurance standards and regulatory oversight. The product complies with European Union marketing authorisation requirements and is distributed through GNH USA's global logistics network.

Desmopressin is used to manage disorders of water balance, particularly conditions involving excessive nighttime urine production. - Nocturnal polyuria (nocturia): reduces urine volume and frequency during sleep, helping improve sleep continuity.

Desmopressin may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Headache: mild to moderate pain often transient. - Nausea: occasional upset stomach. - Mild hyponatraemia: slight reduction in serum sodium. - Abdominal cramps: intermittent discomfort. - Dry mouth: reduced salivation.

Serious or Rare Side Effects: - Severe hyponatraemia: marked low sodium that can lead to confusion or seizures. - Water intoxication: excessive fluid retention causing swelling or pulmonary oedema. - Seizures: neurologic events linked to electrolyte imbalance. - Allergic reactions: rash, itching, or anaphylaxis. - Thrombosis: rare clot formation in veins.

Before prescribing Nocdurna, clinicians should evaluate patient-specific factors and monitor for safety concerns. - Monitor serum sodium: check levels regularly to detect hyponatraemia early. - Adjust dose in renal impairment: reduce dose or increase monitoring frequency. - Limit fluid intake: advise patients to avoid excessive drinking while on therapy. - Use caution in elderly: increased susceptibility to electrolyte disturbances. - Contraindicated in existing hyponatraemia: do not initiate treatment. - Store at below 25°C: keep in the original pack, protect from moisture.

Desmopressin can interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - MAO inhibitors: may potentiate hyponatraemia risk. - Carbamazepine: reduces desmopressin effectiveness. - NSAIDs: increase risk of water retention and hyponatraemia.

Moderate Interactions (Monitor Closely): - SSRIs and other antidepressants: may enhance hyponatraemia. - Diuretics: can alter fluid balance and sodium levels.
