It is an opioid antagonist, which means that it inhibits or reverses the effects of opioid medications. It is mostly used to treat opioid drug overdoses due to its antagonistic properties. Naloxone binds to albumin at a rate of around 45%, although it also strongly interacts with other proteins. In order to stop the effects of opioid drugs, naloxone temporarily inhibits opioid receptors. Because naloxone cannot be used to get high, there is minimal risk that it will be taken without a prescription. There is no evidence that long-term naloxone use can have harmful physiological effects or cause dependence. Users of naloxone do not develop tolerance, and the drug is not known to have contributed to any overdose deaths. This condition primarily affects people in their 20s and 30s. The prodromal phase refers to the time before symptoms appear.
