Which analgesic is derived from opium and used for moderate to severe pain?

• A. Acetaminophen
• B. Ibuprofen
• C. Morphine sulfate
• D. Naproxen

Answer: (C)

Opioid analgesics derived from opium provide strong relief for moderate to severe pain. Morphine sulfate is the classic example, being derived directly from opium and acting on mu receptors to block pain signals, making it suitable for significant pain such as post‑operative or cancer-related pain. The other options are non-opioid analgesics or anti-inflammatories: acetaminophen lacks anti-inflammatory action and is not opioid-derived, while ibuprofen and naproxen are NSAIDs that address pain mainly through inflammation control. Thus, morphine sulfate best fits the description.
