Troxyca ER

Oxycodone/naltrexone is a combination medication made of two medications. Oxycodone is an opioid pain reliever that binds to certain parts of your brain, called mu-opioid receptors, to change how you react to pain. This helps lower how much pain you feel. Naltrexone is an opioid antagonist. It blocks the opioid receptors in your body and prevents you from feeling the effects of opioid medications (e.g., oxycodone). In this combination medication, the purpose of naltrexone is to prevent abuse (when a medication is used for non-medical reasons to bring out desirable physical or emotional effects). It's not active and won't work unless the tablet is crushed, such as in cases of abuse. If crushed, the naltrexone is released and will block the oxycodone from working in your body. For people abusing opioids regularly, this can cause bothersome withdrawal symptoms, such as changes in behavior or mood, chills, muscle aches, restlessness, and yawning.
