Pulsatile Delivery for Controlling Drug Release

Part of the Advances in Delivery Science and Technology book series (ADST)


The mechanisms and modes of drug action are such that systems ­providing constant and persistent plasma levels may not be optimally effective with some drugs and clinical conditions. At times, drug may need to be delivered at a specific time, for a certain period, to a specific location. “Delivery on demand” may even be optimal in response to the presence of a specific “biomarker-type” mediator. There is in consequence much interest in systems that can deliver drug from a unit in a time, location, or stimulus-driven mode. This chapter discusses the potential, possibilities, and limitations for pulsatile delivery so that therapy can meet the above requirements.
