A good example of an anti-abuse formuation of a opioid is the gelling agent in some Oxymorphone tablets.
Another example is the new Oxycontin pills being un-smashable unless special techniques are used.
One last example is Vyvance, literally bound to a amino acid so that it cant be active until the amino acid is metabolized out of the chemical structure. This is rate-limited so at a certain dose threshold the effects dont get stronger, and the duration just gets alot longer.
As you can see, there are many many different ways to prevent abuse of prescription drugs. I can however help you, there should be some numbers, and maybe even letters on the pill. Tell me them, and ill look up the pill and whats including inside. Ill try and see if theres anything that yells "Anti-Abuse".
Get back to me when you can, and ill do my best to help!
