NOCDURNA vs NOCTIVA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Desmopressin is a synthetic analog of vasopressin (antidiuretic hormone) that binds to V2 receptors in the renal collecting ducts, increasing water reabsorption and reducing urine volume.
50 mcg sublingual tablet once daily, 1 hour before bedtime.
Desmopressin acetate: 1-2 sprays (10-20 mcg) intranasally once daily at bedtime; or 0.1-0.2 mg orally once daily at bedtime.

~2.8 hours; short half-life suitable for nocturnal dosing with minimal morning carryover
Terminal elimination half-life is 2-4 hours (mean 3.2 hours) in adults with normal renal function; prolonged to 6-9 hours in moderate renal impairment (CrCl 30-50 mL/min).
Renal: >80% as unchanged drug; fecal: ~10%
Renal excretion of unchanged drug accounts for approximately 70% of the dose; fecal elimination constitutes about 20%, with the remainder as metabolites.
