ABSTRACT:
A transdermal drug delivery patch has an excipient matrix containing an agonist for administration across the skin of a user, with the matrix further containing a plurality of spaced apart hollow cilia filled with an antagonist, whereby if an abuser attempts to physically remove the agonist the cilia will break releasing the antagonist, or if the abuser attempts to use a solvent to remove the agonist the cilia will dissolve releasing the antagonist, thereby blocking the effect the abuser is attempting to attain by concentrating the agonist for oral ingestion or by hypodermic needle injection.
