Abstract

Disclosed is a family of intranasal spray dispensers for administering uniform low doses of desmopressin so as to achieve safe antidiuresis in human patients. The dispensers of the invention may be used in the treatment of nocturia, primary nocturnal enuresis, incontinence, urinary frequency, diabetes insipidus, or any disease or syndrome where desmopressin therapy is useful or where safe temporary suppression of urine production may lead to beneficial health effects or increased convenience in voiding control.

Claims (26)

1 . A method of inducing an anti-diuretic effect in a patient, the method comprising intranasally administering to the patient a composition comprising an intranasal desmopressin dose in the form of a plume ejected over a time interval from the nozzle of a metered dose spray device

the plume comprising a volume of moving droplets together defining a conical volume having a central axis and an apex at the nozzle of the spray device, wherein the droplet density (number of droplets per unit volume) within the conical volume increases in a direction normal to the axis, the droplets together comprising between about 0.05 μg and 5.0 μg desmopressin, the plume serving to increase contact of the droplets with intranasal luminal mucosal surfaces,

wherein the droplets further comprise an oil-in-water emulsion and a permeation enhancer.

2 . The method of claim 1 wherein said permeation enhancer is cyclopentadecanolide.

3 . The method of claim 1 , wherein an axial cross section of the conical volume at a surface about 3 cm or less from its apex describes an annular disk of droplets.

4 . The method of claim 1 wherein the patient is an adult suffering from nocturia and the method treats the nocturia.

5 . The method of claim 4 , wherein the plume is effective to produce a desmopressin blood concentration no greater than 15 +/−3 pg/ml in said adult patient.

6 . The method of claim 1 wherein the plume is effective to produce a desmopressin blood concentration no greater than 15+/−3 pg/ml in said patient.

7 - 9 . (canceled)

10 . The method of claim 1 wherein the droplets together comprise 1.5 μg desmopressin.

11 - 12 . (canceled)

13 . The method of claim 1 wherein the droplets together comprise 0.75 μg desmopressin.

14 - 20 . (canceled)

21 . (canceled)

22 - 50 . (canceled)

51 . The method of claim 2 , wherein the droplets together comprise 0.75 μg desmopressin.

52 . The method of claim 2 , wherein the droplets together comprises 1.5 μg desmopressin.

53 . The method of claim 3 , wherein the droplets together comprise 0.75 μg desmopressin.

54 . The method of claim 3 , wherein the droplets together comprises 1.5 μg desmopressin.

55 . The method of claim 4 , wherein the droplets together comprise 0.75 μg desmopressin.

56 . The method of claim 4 , wherein the droplets together comprises 1.5 μg desmopressin.

57 . The method of claim 5 , wherein the droplets together comprise 0.75 μg desmopressin.

58 . The method of claim 5 , wherein the droplets together comprises 1.5 μg desmopressin.

59 . The method of claim 6 , wherein the droplets together comprise 0.75 μg desmopressin.

60 . The method of claim 6 , wherein the droplets together comprises 1.5 μg desmopressin.

61 . The method of claim 21 , wherein the droplets together comprise 0.75 μg or 1.5 μg desmopressin.
