title: [Controlled-delivery drugs].
abstract: The possibility of using modern means for systemic therapy, requires methods of delivery with the ability to modify such delivery once it has started. Some of these methods are already available as is the case of patches for a variety of indications, providing the passage of the medicine through the skin. Other devices, more complicated and of wide clinical use, may enable controlled liberation of substances directed to specific organs. A brief review of these systems is presented.
