An electrical transdermal drug applicator provides enhanced drug flow to the bloodstream of the subject by delivering a primary drug into a subject's circulatory system for therapeutic purposes, and delivering from the same or other reservoir a non therapeutic counteracting agent to the skin of the patient which induces flow enhancement and allows delivery of the primary drug systemically over a longer period of time and in greater quantity than heretofore appeared possible using electric current.

Why it's free to use
- Filed February 11, 1992 and granted October 31, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 11, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 11, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
