Which of the following is classified as a nonsteroidal anti-inflammatory drug (NSAID)?

Naproxen is classified as a nonsteroidal anti-inflammatory drug (NSAID) because it works by inhibiting the enzymes COX-1 and COX-2, which are involved in the formation of prostaglandins. Prostaglandins are compounds that mediate inflammation, pain, and fever in the body. By blocking these enzymes, naproxen effectively reduces inflammation, alleviates pain, and lowers fever, making it a go-to medication for conditions such as arthritis, muscle pain, and menstrual cramps.

The other options listed—oxycodone, hydromorphone, and Percocet—are all classified as opioid analgesics. Oxycodone and hydromorphone are potent pain relief medications that belong to the opioid category and primarily work by binding to opioid receptors in the brain to alter the perception of pain. Percocet, which combines oxycodone with acetaminophen, functions as a pain reliever but does not fall under the NSAID classification. Understanding the classification of these medications is crucial for recognizing their appropriate uses and potential side effects in patient care.
