Claim:
1. A system for transdermal delivery of active agents for therapeutic and medicinal purposes, the system comprising: a power source that generates a charged balanced alternating output current that varies between a first current value and a second current value; a pair of electrode assemblies comprising a first electrode assembly and a second electrode assembly, each electrode assembly applied to a corresponding skin layer of a user, and wherein each electrode assembly includes an electrode that is coupled to the power source to receive the output current; and wherein at least one of the electrode assemblies in the pair includes a medium that carries an active agent having a charge, the medium being provided on the at least one electrode assembly to enable the corresponding received output current to alternatively repel the active agent into the skin layer from the at least one electrode assembly for a duration in which the output current has a polarity that is the same as a polarity of the active agent, wherein the output current is generated according to an asymmetrical waveform so that a duration in which the output current has the polarity that is the same as the polarity of the active agent is longer than a duration when a minimum value of the output current is zero or negative.
