DESMOPRESSIN ACETATE PRESERVATIVE FREE vs NOCDURNA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic analog of antidiuretic hormone (ADH, vasopressin) that binds to V2 receptors in renal collecting ducts, increasing water permeability and reabsorption, thereby reducing urine volume and increasing urine osmolality. Also increases factor VIII and von Willebrand factor levels via V2 receptor activation on endothelial cells.
NOCDURNA (desmopressin) is a synthetic analog of vasopressin, an antidiuretic hormone. It acts on V2 receptors in the renal collecting ducts to increase water reabsorption, reducing urine production.
0.2-0.4 mg (200-400 mcg) orally once daily at bedtime, or 0.1-0.2 mg (100-200 mcg) orally two to three times daily. Alternatively, 1-4 mcg (0.001-0.004 mg) intravenously or subcutaneously once daily.
50 mcg sublingual tablet once daily, 1 hour before bedtime.

1.5-2.5 hours (terminal elimination half-life); prolonged in renal impairment (up to 5-6 hours in severe renal failure).
~2.8 hours; short half-life suitable for nocturnal dosing with minimal morning carryover
Primarily renal (filtration and tubular secretion); approximately 60-70% of the administered dose is excreted unchanged in urine; minor biliary/fecal elimination (<5%).
Renal: >80% as unchanged drug; fecal: ~10%
