Abstract:
1. A transdermal patch having an on-board energy storage device for coupling to an external power source in order to store a charge in the energy storage device, comprising: a dermal contact layer having an adhesive suitable for securing the dermal contact layer to a skin of a user; a drug source supported by the dermal contact layer for transdermal delivery of a drug through the skin of the user; an electrically-actuatable porator disposed so as to substantially or completely overlie the drug source; a removable carrier, wherein the porator is supported by the carrier and is removable therewith, the porator being removable by a pulling movement from a rest position in which the porator substantially or completely overlies the drug source to a second position; the chargeable energy storage device being selectively electrically connectable to the porator so as to discharge the stored charge and thereby actuate the porator; and a switch connected between the energy storage device and the porator for making the selective electrical connection to the porator, the switch comprising a stationary pole and an arm mounted for movement by the user relative to the pole.
