The time of abstinence may be shorter than 7 days, depending on the half-life of the specific opioid taken. Some physicians use a naloxone challenge to determine whether an individual has any opioids remaining. The challenge involves giving a test dose of naloxone and monitoring for opioid withdrawal.

In combination with agonists of the MOR such as morphine however, naltrexone appears to become an inverse agonist of the MOR. Conversely, naltrexone remains a neutral antagonist of the KOR and DOR. In contrast to naltrexone, 6β-naltrexol is purely a neutral antagonist of the opioid receptors.
