Application Number:	11/327,016
Patent Claims:	1. A system for transdermal delivery of a peptide or polypeptide from a dried pharmaceutical composition comprising: (i) an apparatus for facilitating transdermal delivery of a peptide or polypeptide through skin of a subject, said apparatus comprises: (a) an electrode cartridge comprising at least one electrode; and (b) a main unit comprising a control unit which is adapted to apply electrical energy to the electrode when the electrode is in vicinity of the skin, typically generating current flow or one or more sparks, enabling ablation of stratum corneum in an area beneath the electrode, thereby generating at least one micro-channel in the area on the skin of the subject; and (ii) a patch comprising a non-adhesive liner and a dried pharmaceutical composition comprising a peptide or polypeptide having up to two hundred amino acid residues, wherein the dried pharmaceutical composition is present upon the non-adhesive liner. 2. The system according to claim 1, wherein the peptide is calcitonin. 3. The system according to claim 2, wherein the peptide is salmon calcitonin. 4. The system according to claim 1, wherein the peptide is parathyroid hormone (PTH). 5. The system according to claim 4, wherein the peptide is human PTH (hPTH). 6. The system according to claim 5, wherein the peptide is hPTH (1-34). 7. The system according to claim 1, wherein the pharmaceutical composition further comprises a stabilizer. 8. The system according to claim 7, wherein the stabilizer is a carbohydrate selected from the group consisting of glucose, galactose, raffinose, cellobiose, gentiobiose, sucrose and trehalose. 9. The system according to claim 1, wherein the pharmaceutical composition further comprises an acidic component to yield a pH in the range from about 3 to about 6 in solution before drying. 10. The system according to claim 9, wherein the pharmaceutical composition comprises hPTH (1-34), sucrose and acetic acid to yield a pH of about 4.0 in solution before drying. 11. The system according to claim 9, wherein the pharmaceutical composition comprises hPTH (1-34), trehalose and citric acid to yield a pH of about 4.0 in solution before drying. 12. The system of claim 1, wherein the patch is a printed patch comprising a uniform distribution of dried solid dots of the pharmaceutical composition present upon the non-adhesive liner. 13. The system according to claim 12, wherein the peptide is calcitonin. 14. The system according to claim 13, wherein the peptide is salmon calcitonin. 15. The system according to claim 12, wherein the peptide is parathyroid hormone (PTH). 16. The system according to claim 15, wherein the peptide is human PTH (hPTH). 17. The system according to claim 16, wherein the peptide is hPTH (1-34). 18. The system according to claim 12, wherein the pharmaceutical composition further comprises a stabilizer. 19. The system according to claim 18, wherein the stabilizer is a carbohydrate selected from the group consisting of glucose, galactose, raffinose, cellobiose, gentiobiose, sucrose and trehalose. 20. The system according to claim 12, wherein the pharmaceutical composition further comprises an acidic component to yield a pH in the range from about 3 to about 6 in solution before drying. 21. The system according to claim 20, wherein the pharmaceutical composition comprises hPTH (1-34), sucrose and acetic acid to yield a pH of about 4.0 in solution before drying. 22. The system according to claim 20, wherein the pharmaceutical composition comprises hPTH (1-34), trehalose and citric acid to yield a pH of about 4.0 in solution before drying. 23. A method for transdermal administration of a dried pharmaceutical composition comprising a peptide or polypeptide by the system of claim 1, the method comprising: (a) generating at least one micro-channel in an area of the skin of a subject by the apparatus, and (b) affixing the patch upon the micro-channel generated area to administer the pharmaceutical composition by dissolving it in fluids that are exuded from the skin through the micro-channel(s). 24. The method according to claim 23 further comprising: (c) achieving a therapeutic blood concentration of the peptide or polypeptide for a predetermined period of time. 25. The method according to claim 23, wherein the peptide is calcitonin. 26. The method according to claim 25, wherein the peptide is salmon calcitonin. 27. The method according to claim 23, wherein the peptide is parathyroid hormone (PTH). 28. The method according to claim 27, wherein the peptide is human PTH. 29. The method according to claim 28, wherein the peptide is hPTH (1-34). 30. The system according to claim 1, wherein the electrode cartridge is removable. 31.
