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.
Claims23
A transdermal drug delivery patch for the delivery of a drug across the skin of a user comprising:
- a main body providing an occlusive covering on the skin of a user, including:
- an outer face;
- an inner face forming a hollow cavity;
- a plurality of cilia projecting from said inner face into said hollow cavity, said plurality of cilia being spaced apart and each having a hollow tubular core;
- an excipient matrix filling portions of said cavity between said plurality of cilia;
- an agonist contained in said matrix;
- an antagonist contained within said plurality of cilia, respectively, whereby said plurality of cilia are formed from material that will either rupture if attempts are made by a user to physically remove the matrix or dissolve out the agonist through use of a solvent, whereby upon rupture or dissolvement of said plurality of cilia, they release their associated antagonist to block the desired effect an abuser is attempting to obtain by concentrating said agonist to ingest it orally or through injection;
- and
- means for securing said main body to a desired location on the skin of a user.
