Which item is NOT a classification of opioids?

• A. Naturally occurring opiates
• B. Semisynthetic opioids
• C. Synthetic opioids
• D. Opioid antagonists

Answer: (D)

Opioids are grouped by origin and chemical makeup into naturally occurring opiates, semisynthetic opioids, and synthetic opioids. Naturally occurring opiates include drugs like morphine and codeine. Semisynthetic opioids are derived from natural opiates, such as heroin, hydrocodone, and oxycodone. Synthetic opioids include fully man-made drugs like fentanyl and methadone. Opioid antagonists, such as naloxone and naltrexone, are not opioids themselves; they block opioid receptors to reverse or prevent opioid effects. That’s why the item describing an opioid antagonist does not fit as a classification of opioids.
