Uses This medication is used to prevent people who have been addicted to certain drugs (opiates) from taking them again
It is an opioid
Opioid antagonists, such as naltrexone, bind to opiate receptors and block the action of both opioid medications and opiate neurotransmitters
Fentanyl and other highly potent synthetic opioids are very strong opioids that are known to be mixed into a variety of substances such as Bunavail (buprenorphine and naloxone) buccal film Cassipa (buprenorphine and naloxone) sublingual film Vivitrol (naltrexone for extended-release injectable suspension) intramuscular
(+)-Naloxone (dextro-naloxone) is a drug which is the opposite enantiomer of the opioid antagonist drug (−)-naloxone
Food and Drug Administration (FDA) announced the approval of the first nonprescription naloxone product, Narcan 4 milligram (mg) naloxone hydrochloride nasal spray
Buprenorphine/naloxone, sold under the brand name Suboxone among others, is a fixed-dose combination medication that includes buprenorphine and naloxone
Naltrexone can treat alcohol use disorder and opioid use disorder, but it isn’t used in
