Device for transdermal electrotransport delivery of fentanyl and sufentanil |
| abstract |
The invention provides a formulation for electrotransport delivery of an analgesic drug (e.g. fentanyl). Also provided is an improved electrotransport drug delivery system for analgesic drugs, namely fentanyl and sufentanil. The fentanyl/sufentanil is provided as a water-soluble halide salt (e.g., fentanyl hydrochloride), preferably contained in a hydrogel formulation for use in an electrotransport device (10). In accordance with the present invention, the donor electrode (22) of the electrotransport delivery device (10) is comprised of silver and the donor reservoir (26) is substantially free of supplementary chloride ion sources and contains a predetermined "excess" loading of fentanyl/sufentanil halide to prevent silver ion migration with attendant skin discoloration. |
