Which medication is classified as a narcotic analgesic?

• A. Nalbuphine
• B. Metoclopramide
• C. Hydroxyzine
• D. Prochlorperazine

Answer: (A)

Nalbuphine is classified as a narcotic analgesic because it acts on opioid receptors in the brain to provide pain relief. It is specifically a mixed agonist-antagonist, meaning that it can stimulate opioid receptors to alleviate pain while also having the ability to block other receptors to prevent certain side effects associated with stronger narcotics. This characteristic makes it useful in managing moderate to severe pain while having a lower risk of respiratory depression compared to full agonists like morphine. In contrast, metoclopramide, hydroxyzine, and prochlorperazine serve different roles in medical treatment. Metoclopramide is primarily an antiemetic used to treat nausea and vomiting. Hydroxyzine is an antihistamine generally used for anxiety reduction and allergies. Prochlorperazine, while it can be used to treat severe nausea and vomiting, is also categorized similarly as an antipsychotic medication, not a narcotic analgesic. Thus, when considering medications that specifically function as narcotic analgesics, nalbuphine stands out as the correct choice.
