Title:	Pharmaceutical formulations of desmopressin
Abstract:	Good bioavailability of desmopressin can be obtained with an orodispersible pharmaceutical dosage form. Preferred dosage forms comprise desmopressin and an open matrix network which is an inert water-soluble or water-dispersible carrier material. Desmopressin formulated in this way is useful for voiding postponement, or the treatment or prevention of incontinence, primary nocturnal enuresis (PNE), nocturia or central diabetes insipidus. Peptides other than desmopressin can also be formulated in this way.

Patent Claims:	1. An orodispersible pharmaceutical dosage form of desmopressin comprising: desmopressin in a form selected from one or more of the free base of desmopressin and a pharmaceutically acceptable salt thereof, in an amount measured as the free base, selected from 25 .mu.g and 50 .mu.g, and one or more carriers, wherein at least one carrier is gelatin in an open matrix network structure, wherein the dosage form exhibits a mean elimination half-life of desmopressin after administration of about 2.8 to 3 hours after the maximum plasma concentration is reached. 2. The dosage form according to claim 1, wherein the gelatin is fish gelatin. 3. The dosage form according to claim 1, wherein the gelatin is non-gelling fish gelatin. 4. The dosage form according to claim 1, further comprising mannitol. 5. The dosage form according to claim 1, further comprising citric acid. 6. An orodispersible pharmaceutical dosage form of desmopressin comprising: desmopressin in a form selected from one or more of the free base of desmopressin and a pharmaceutically acceptable salt thereof, in an amount measured as the free base, selected from 25 .mu.g and 50 .mu.g, and one or more carriers, wherein at least one carrier is gelatin in an open matrix network structure, wherein the dosage form exhibits a desmopressin bioavailability after administration of from greater than 0.1% to 0.38%. 7. The dosage form according to claim 6, wherein the gelatin is fish gelatin. 8. The dosage form according to claim 6, wherein the gelatin is non-gelling fish gelatin. 9. The dosage form according to claim 6, further comprising mannitol. 10. The dosage form according to claim 6, further comprising citric acid. 11. An orodispersible pharmaceutical dosage form of desmopressin comprising: desmopressin in a form selected from one or more of the free base of desmopressin and a pharmaceutically acceptable salt thereof, in an amount measured as the free base, selected from 25 .mu.g and 50 .mu.g, and one or more carriers, wherein at least one carrier is gelatin in an open matrix network structure, wherein the dosage form exhibits a desmopressin bioavailability of from 0.23% to 0.38%. 12. The dosage form according to claim 11, wherein the gelatin is fish gelatin. 13. The dosage form according to claim 11, wherein the gelatin is non-gelling fish gelatin. 14. The dosage form according to claim 11, further comprising mannitol. 15. The dosage form according to claim 11, further comprising citric acid.
