Which of the following is an example of a non-narcotic analgesic?

Ibuprofen is classified as a non-narcotic analgesic because it belongs to a group of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). These medications are commonly used to relieve mild to moderate pain, reduce inflammation, and lower fever. Unlike narcotics, which are opioids and have a higher potential for abuse and dependence, ibuprofen works by inhibiting enzymes (COX-1 and COX-2) involved in the inflammatory process, which helps to alleviate pain without the addictive properties associated with narcotics.

The other options presented are all narcotic analgesics or opioids, known for their potency in managing severe pain but also for their potential for dependence and side effects.
