Are you referring to a patch different from the one which was approved in March of this year (EMSAM). It is now approved, but won't be distributed to all wholesalers until later this year.
I asked about this a few months ago...it is effective, but the side effects which limit oral dosing are apparent at all but the lowest patch strength (there are 3 I think) which will limit its usefulness.
It is marketed by Bristol-Meyers Squibb so their site will have the references which were used for approval.
