The present invention is directed to a pharmaceutical composition comprising 0.5 ng to 20 μg desmopressin and a pharmaceutically acceptable carrier. The present invention is also directed to a pharmaceutical composition comprising desmopressin and a pharmaceutically acceptable carrier, wherein the pharmaceutical composition is effective to establish a steady plasma/serum desmopressin concentration in the range of from about 0.1 picograms desmopressin per mL plasma/serum to about 10.0 picogram desmopressin per mL plasma/serum. Articles of manufacture and methods of using the above invention are also disclosed.
1. A patch adapted for intradermal administration of desmopressin to a patient, the patch comprising desmopressin and a pharmaceutically acceptable carrier in a dosage form that dispenses from 0.5 ng up to 2 μg desmopressin intradermally.
2. The patch of claim 1 , wherein the patch comprises a depot of desmopressin.
3. The patch of claim 1 , wherein the dosage form is formulated to establish a plasma/serum desmopressin concentration within the range from about 0.1 picograms desmopressin per ml plasma/serum to a maximum of 10.0 picograms per ml plasma/serum and to decrease urine production.
4. The patch of claim 3 , wherein the dosage form is formulated to establish a plasma/serum desmopressin concentration within the range from about 0.5 picograms desmopressin per ml plasma/serum to a maximum of 5.0 picograms per ml plasma/serum.
5. The patch of claim 3 , wherein the dosage form is formulated to establish a plasma/serum desmopressin concentration within the range from about 0.1 picograms desmopressin per ml plasma/serum to a maximum of 10.0 picograms per ml plasma/serum for a time between four and six hours.
6. The patch of claim 1 , wherein the dosage form is effective to produce an antidiuretic effect lasting for a maximum of between about 4 and about 6 hours.
