Abstract
The present invention describes a system and method for reducing the abuse potential of drugs, particularly or especially narcotic agents, in transdermal drug delivery systems. This is achieved by designing the transdermal drug delivery system such that when the active drug is extracted out of the transdermal delivery system, a deterrent agent is also timely co-extracted upon introduction of the system to an extraction solution where abuse may normally be allowed take place. Preferably, the deterrent agent of the present invention is capable of inducing or causing one or more intensely repugnant effects within the abusing person, thus reducing the potential for abuse of the active drug formulation.
