摘要：
Embodiments of the invention provide an architecture, system and methods for optimizing power utilization for transdermal iontophoretic drug delivery which maintain a iontophoretic driving voltage at a reduced or even minimum value to support an iontophoretic delivery current. The reduced voltage reduces the power requirements for a transdermal iontohoretic delivery system during a period of drug delivery. Embodiments of an architecture for implementing this approach can utilize a controller which compares the desired current to the actual current and adjusts the voltage to reduce the amount of power used for iontophoretic drug delivery. The controller can comprise a state machine or microprocessor. Embodiments of the invention are particularly useful for extending the battery life of transdermal iontophoretic drug delivery systems.
