  • Publication number: 20190111051
    Abstract: Abuse-resistant, controlled release opioid tablets are a combination containing an opioid antagonist such as naloxone at a level above that needed to suppress the euphoric effect of the opioid, if the combination were crushed to break the controlled release properties causing the opioid and opioid antagonist to be released as a immediate release product as a single dose. The controlled release nature of the table prevents the accumulation of orally effective amounts of opioid antagonist when taken normally. The opioid antagonist is contained in a controlled-release matrix and released, over time, with the opioid.
