Nictur (Desmopressin Acetate)

Desmopressin, the active ingredient in Nictur, is an antidiuretic hormone analog presented as an oral tablet for oral use. It is used to manage central diabetes insipidus, nocturnal enuresis, and mild hemophilia A or von Willebrand disease.

GNH USA supplies Nictur as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Desmopressin acts on the antidiuretic pathway and is indicated for the following conditions: - Central diabetes insipidus: reduces excessive urine production and helps maintain water balance. - Nocturnal enuresis: decreases nighttime urine output, aiding in bladder control. - Mild hemophilia A and von Willebrand disease: raises plasma levels of factor VIII and von Willebrand factor to improve clotting.

Desmopressin may cause a range of adverse reactions, which are grouped by frequency and severity.

Common Side Effects: - Headache: mild to moderate pain in the head. - Nausea: upset stomach or urge to vomit. - Nasal congestion: feeling of a blocked nose.

Serious or Rare Side Effects: - Severe hyponatremia: can cause seizures, coma, or death. - Water intoxication: excessive fluid retention leading to edema and neurological symptoms. - Allergic reaction: rash, itching, swelling, or anaphylaxis.

Before starting Nictur, several precautions should be considered: - Dose adjustment: use lower doses in patients with renal impairment. - Fluid restriction: limit fluid intake to reduce risk of hyponatremia. - Monitor electrolytes: regularly check serum sodium during therapy. - Avoid in uncontrolled hypertension: may exacerbate blood pressure. - Pregnancy and lactation: use only if clearly needed, as safety data are limited. - Store at ambient temperature: keep below 25°C, protect from moisture and light.

Desmopressin can interact with other medicines; interactions are categorized by their clinical significance.

Major Interactions (Avoid): - Carbamazepine: reduces desmopressin efficacy. - Other antidiuretic agents (e.g., chlorpropamide): increases risk of hyponatremia. - High‑dose NSAIDs (e.g., ibuprofen): may potentiate water retention.

Moderate Interactions (Monitor Closely): - ACE inhibitors or ARBs: may enhance antidiuretic effect, monitor sodium. - Diuretics (thiazides): can alter fluid balance, watch electrolytes. - SSRIs (selective serotonin reuptake inhibitors): potential additive effect on serum sodium.
