What is XR-NTX?

XR-NTX, or extended-release naltrexone, is specifically designed as a long-term injectable form of naltrexone. This medication is primarily utilized in the treatment of alcohol dependence and opioid use disorder. By providing an extended-release formulation, XR-NTX allows for less frequent dosing compared to oral naltrexone, which requires daily administration. This can enhance adherence to treatment regimens as patients only need to receive the injection every four weeks, making it more convenient for those managing these conditions.

In comparison, the other options relate to different types of medications or administration routes that do not accurately describe XR-NTX. For instance, an oral medication taken daily doesn’t capture the long-acting injectable nature of XR-NTX. Similarly, describing it as a medication for chronic pain misrepresents its primary uses, and classifying it as a stimulant is incorrect because naltrexone functions as an opioid antagonist rather than a stimulant, which typically increases alertness or energy levels. Thus, the correct characterization of XR-NTX as a long-term injectable form of naltrexone accurately reflects its intended use and formulation.
