ABSTRACT:
A drug delivery system for transdermally delivering drugs through a given skin area is provided. The delivery system comprises a collapsible container for containing the drug. The container has a drug release opening. A displaceable member is in engagement with the container for expelling the drug from the container via the release opening. A driver is connected with said displaceable member so as to drive the same towards the collapsible container. Conduits are disposed between the release opening and the skin area for conducting the drug to the skin area. An ultrasonic transducer is disposed in the general conduit area for generating ultrasonic waves aimed at the skin area. An ultrasonic waveform generator drives the transducer and an electric control circuit is connected to the flow control for electrically activating the flow control.
