Pharmaceutical compositions including low dosages of desmopressin
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 method of treating nocturia, primary nocturnal enuresis, or incontinence, or for inducing voiding postponement, said method comprising administering to a patient in need thereof a pharmaceutical composition comprising a dose of desmopressin sufficient to achieve a maximum desmopressin plasma/serum concentration no greater than 10 pg/ml and maintaining the concentration within the range of about 0.5 pg/ml and 10 pg/ml for about four to six hours.
2. The method of claim 1 , comprising administering said composition by transmucosal, transdermal, or intradermal delivery.
3. The method of claim 1 , comprising treating nocturia.
4. The method of claim 1 , comprising administering said composition by intravenous delivery.
5. The method of claim 1 , comprising administering said composition by subcutaneous delivery.
6. The method of claim 1 , comprising administering said composition by transmucosal delivery.
7. The method of claim 1 , comprising administering said composition by transdermal delivery.
8. The method of claim 1 , comprising administering said composition by intradermal delivery.
9. The method of claim 1 , wherein the desmopressin plasma/serum concentration is maintained at a level no greater than about 5 pg/ml.
10. A method for inducing an antidiuretic effect in a patient comprising the step of administering to a patient a pharmaceutical composition comprising desmopressin by transmucosal, transdermal, or intradermal delivery in an amount and for a time sufficient to establish a maximum serum/plasma desmopressin concentration no greater than 10 pg/ml.
11. The method of claim 10 , wherein said patient is suffering from incontinence, primary nocturnal enuresis (PNE), or nocturia.
12. The method of claim 10 , wherein said desmopressin pharmaceutical composition is administered in an amount and for a time sufficient to establish a serum/plasma desmopressin concentration no greater than about 5 pg/ml.
13. A method for treating a patient suffering from nocturia comprising administering to a patient a pharmaceutical composition comprising desmopressin by transmucosal, transdermal, or intradermal delivery in an amount and for a time sufficient to establish a maximum serum/plasma desmopressin concentration greater than 0.1 pg/ml and less than 10 pg/ml.
14. The method of claim 10 , wherein the patient is a human or other mammalian subject.
15. The method of claim 13 , wherein said concentration is maintained greater than 0.1 pg/ml for a time greater than 4 hours.
