Which non-opioid analgesic is commonly used for mild to moderate pain and lacks anti-inflammatory properties?

• A. Acetaminophen
• B. Ibuprofen
• C. Naproxen
• D. Celecoxib

Answer: (A)

Acetaminophen is used for mild to moderate pain and fever without providing anti-inflammatory effects because it acts mainly in the central nervous system and does not significantly inhibit peripheral prostaglandin synthesis involved in inflammation. This makes it non-opioid and non-anti-inflammatory, fitting the scenario described. The other options are NSAIDs or related drugs that reduce inflammation through COX enzyme inhibition, so they do have anti-inflammatory properties. Ibuprofen and naproxen are classic NSAIDs with anti-inflammatory effects, while celecoxib is a COX-2 inhibitor with anti-inflammatory action. A note on safety: acetaminophen should be used within recommended daily limits to avoid liver toxicity, especially in people with liver disease or those who consume alcohol regularly.
