First Claim
Patent Images
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.
