Abstract
A combination of a pro-agonist first medication in timed release form, and a sequestered second non-antagonist medication allows the first medication to be effective if taken according to medical directions. If the combination is tampered with or otherwise taken in a manner not according to medical directions, the second medication is released and prevents the first medication from becoming effective. The non-antagonist second medication does not precipitate immediate withdrawal in a dependent patient.
