Does naltrezone show up on a drug test?

Answer 1

I believe you mean naltrexone. In the world of opiates, there are three major categories. 1. Agonists 2. Antagonists 3. Agonist/Antogonists An agonist is a medication, for example - Morphine, which attaches to an opiate receptor and results in pain relief, along with other actions, such as sedation, euphoria, etc. depending upon which type of opiate receptor it attaches to. An Antogonist is a medication like naltrexone, which will reverse the effect of a medication like morphine by competing for the receptor with morphine, and not allowing the agonist to work, reversing the effect of the morphine. An agonist/Antogonist is a medication like nalbuphine (Nubain) which will act differently, depending on the circumstances. If an agonist (morphine) is present in the system already, this class of medication will act like an Antogonist, thus reversing the effects of the morphine. If no agonist is present, then it will have an agonist effect and cause pain relief, etc. To answer your question, I believe it would depend upon the specific drug test, and how sensitive the particular test is for the various classes of opiates. Most tests that I am aware of check for many different opiates specifically, such as morphine, hydrocodone, oxycodone, codeine, heroin, etc. I am unaware of any testing specifically for naltrexone, but it certainly could be tested for, depending upon why the particular test is being done and the clinical circumstances.
