Desmopressin is a synthetic analog of antidiuretic hormone (ADH) that increases water reabsorption in the renal collecting ducts by binding to V2 receptors, leading to increased aquaporin-2 expression and reduced urine output.
Desmopressin is a synthetic analogue of vasopressin (antidiuretic hormone, ADH) that acts on V2 receptors in renal collecting ducts, increasing water reabsorption and reducing urine output. It also raises plasma levels of factor VIII and von Willebrand factor via V2 receptor stimulation on endothelial cells.

Central diabetes insipidus,Primary nocturnal enuresis,Hemophilia A with factor VIII levels >5%,von Willebrand disease (type I)
Adults: 1-2 sprays intranasally (10 mcg each) once daily; for diabetes insipidus, 1-2 sprays once or twice daily. Oral: 0.1-0.2 mg three times daily.
10 mg orally once daily
Terminal elimination half-life: 2–3 hours (intravenous, subcutaneous); 3–5 hours (oral). Clinical context: Short half-life necessitates frequent dosing; duration of antidiuretic effect may outlast plasma levels due to receptor binding.
Terminal half-life: 8-12 hours; extended in renal impairment (up to 24 hours).
Primarily metabolized in the liver; CYP450 enzymes not significantly involved.
Metabolized primarily by reduction of disulfide bonds; not extensively metabolized by CYP450 enzymes.
Renal (primarily as unchanged drug via glomerular filtration and tubular secretion; ~65% of an intravenous dose excreted unchanged in urine within 24 hours); fecal (~5–10% of an oral dose); minimal biliary elimination.
Renal: ~70% unchanged; biliary/fecal: ~30% as metabolites.
Approximately 1% bound to plasma proteins (negligible binding; primarily to albumin).
95%; primarily binds to albumin and alpha-1-acid glycoprotein.
0.2–0.3 L/kg. Clinical meaning: Low Vd indicates limited extravascular distribution; mostly confined to extracellular fluid.
Vd: 0.5-0.7 L/kg; indicates moderate tissue distribution.
Oral: 0.1–0.5% (low due to enzymatic degradation in GI tract and extensive first-pass metabolism); Subcutaneous: ~85–90%; Intranasal: ~3–5% (variable due to nasal absorption and metabolism).
Oral: 85-90% with food; 70-80% fasting.
GFR >50 m L/min: No adjustment. GFR 10-50 m L/min: Caution, reduce dose by 50% or extend interval. GFR <10 m L/min: Contraindicated or avoid use.
No adjustment required for GFR ≥30 m L/min; contraindicated if GFR <30 m L/min
Child-Pugh A: No adjustment. Child-Pugh B: Reduce dose by 50%. Child-Pugh C: Avoid use.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose to 5 mg once daily; Child-Pugh C: contraindicated
Intranasal: Infants and children, 5 mcg (0.5 spray) once daily, titrate to effect. Oral: 0.05-0.1 mg three times daily, weight-based (0.1-1 mcg/kg) but not established.
Not recommended for use in pediatric patients
Initiate at lowest effective dose; monitor for hyponatremia and fluid retention; adjust based on renal function.
Initiate at 5 mg once daily; monitor renal function closely
No FDA black box warning.

Hypersensitivity to desmopressin or any component,Moderate to severe renal impairment (Cr Cl <50 m L/min),Hyponatremia or history of hyponatremia,Primary polydipsia,Patients on diuretics or other drugs that increase risk of hyponatremia
Avoid excessive fluid intake, especially water, within 1 hour before and after dosing. Limit foods with high water content (e.g., soups, melons). No specific food-drug interactions; focus on fluid restriction to prevent hyponatremia.
Avoid concurrent intake of large volumes of water or hypotonic fluids. Alcohol may reduce antidiuretic effect. Caffeine may increase urine output. Grapefruit juice may enhance absorption of oral formulations.
Desmopressin (MINIRIN) is classified as FDA Pregnancy Category B. No teratogenic effects have been observed in animal studies. In humans, limited data show no increased risk of major birth defects. However, due to antidiuretic effects, monitor for hyponatremia and fluid overload during pregnancy, particularly in third trimester when plasma volume increases.
Desmoda is contraindicated in pregnancy. First trimester: Risk of major congenital malformations (neural tube defects, cardiovascular anomalies) due to folate antagonism. Second/Third trimester: Fetal growth restriction, oligohydramnios, premature closure of ductus arteriosus (if NSAID component).
Desmopressin is excreted into breast milk in very small amounts; M/P ratio is approximately 0.3. It is generally considered compatible with breastfeeding. Because it is a peptide, oral bioavailability in the infant is low. Monitor infant for signs of water retention or electrolyte imbalance, though risk is minimal.
Excreted in breast milk. M/P ratio not established. Avoid breastfeeding due to potential for serious adverse reactions (e.g., folate deficiency, kernicterus) in the infant.
During pregnancy, plasma volume increases and clearance of desmopressin may increase. No standard dose adjustment is required, but patients with diabetes insipidus may need dose titration based on urine output and serum sodium. Avoid overcorrection of hyponatremia. Postpartum, dose should be reduced due to rapid fluid shifts.
Contraindicated in pregnancy. No dose adjustment recommended; avoid use. If accidental exposure occurs, discontinue immediately and initiate folate rescue therapy.
Desmopressin (Minirin) is a synthetic analog of vasopressin; avoid use in patients with hyponatremia or impaired renal function. Monitor sodium levels especially in elderly and young children. Intranasal absorption may be variable with nasal congestion; consider using oral or injectable forms in such cases. For nocturnal enuresis, restrict fluids 1 hour before dose to reduce hyponatremia risk.
Desmopressin is a synthetic analog of vasopressin used for central diabetes insipidus and nocturnal enuresis. Monitor serum sodium, especially in elderly or patients with fluid/electrolyte imbalance. Avoid in patients with hyponatremia or renal impairment. Tachyphylaxis may occur; dose adjustment may be needed. Intranasal route may be less reliable due to mucosal variability.
Do not drink more than 250 m L (8 oz) of fluids within 1 hour before or after taking Minirin to prevent water intoxication.,For intranasal spray, prime pump before first use or if not used for >1 week. Blow nose gently before administration.,Take exactly as prescribed; do not increase dose without consulting your doctor.,Report signs of hyponatremia: headache, nausea, vomiting, confusion, seizures, or unusual fatigue.,If using for bedwetting, take at bedtime and ensure voiding just before sleep.
Take exactly as prescribed; do not exceed dose to avoid water intoxication.,Fluid restriction is critical: limit fluid intake for 1-2 hours after dosing, especially at night.,Report symptoms of hyponatremia: headache, nausea, vomiting, confusion, seizures.,For enuresis, take last dose at bedtime; avoid drinking 1 hour before and 8 hours after.,Intranasal formulations: administer alternately in each nostril; clear nasal passages before use.
