ABUSE RESISTANT DRUG FORMS
First Claim
1. A sustained-release, abuse-resistant oral drug dosage form comprising at least two populations of drug-resin complex particles, wherein the first population of drug-resin complex particles is a sustained-release form comprising an analgesically effective amount of an opioid drug bound to a water-insoluble, pharmacologically inert matrix, said first population of drug-resin complex particles further comprising a water-permeable coating, and wherein the second population of drug-resin complex particles comprises an aversive agent in an amount sufficient to deter abuse if tampered with and a polymeric coating sufficient to substantially prevent release of the aversive agent under normal use conditions.

Abstract
The invention is directed to oral drug dosage forms designed to reduce the abuse potential of an oral dosage form of an opioid analgesic. The oral drug dosage form comprises a first population of drug-resin complex particles comprising an analgesically effective amount of an opioid drug, said first population of particles coated with a water-permeable diffusion barrier coating. The oral drug dosage form further comprises a second population of ion exchange-resin complex particles comprising an aversive agent, said second population of particles coated with a polymer coating sufficient to substantially prevent release of the aversive agent under normal use conditions. The aversive agent is present in an amount effective to partially or substantially deny the drug abuser the euphoric effect and/or cause an aversive effect in the user.
