Which of the following is NOT considered a narcotic medication?

Ibuprofen is classified as a nonsteroidal anti-inflammatory drug (NSAID) and is not considered a narcotic medication. It is primarily used to relieve pain, reduce inflammation, and lower fever. Narcotic medications, also known as opioids, function by binding to opioid receptors in the brain and spinal cord to alter the perception of pain and produce feelings of euphoria.

In contrast, fentanyl, Demerol (meperidine), and morphine all belong to the class of opioids. These medications are prescribed for managing moderate to severe pain and are known for their stronger effects on pain relief and potential for dependence or abuse. Therefore, within the options provided, ibuprofen stands out as the only non-narcotic medication.
