what is an example of an opioid reversal agent?

An example of an opioid reversal agent is naloxone. Naloxone is an opioid antagonist that rapidly reverses opioid overdose by binding to opioid receptors and blocking the effects of opioids such as heroin, fentanyl, oxycodone, and morphine. It can be administered by intranasal spray, intramuscular, subcutaneous, or intravenous injection. Another FDA-approved opioid reversal agent is nalmefene. Both medications are lifesaving and used to counteract opioid overdoses effectively.
