Which drug is commonly taken for arthritis?

The correct choice for a commonly taken drug for arthritis is naproxen. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that helps relieve pain, reduce inflammation, and lower fever. It is often prescribed for conditions like arthritis because it targets inflammation, which is a significant factor in arthritic conditions. It works by inhibiting the enzymes that contribute to the production of prostaglandins, substances in the body that mediate inflammation and pain.

While acetaminophen is often used for pain relief, it does not have the anti-inflammatory properties that are crucial for treating arthritis effectively. Celecoxib is another NSAID that may be prescribed for arthritis but is specifically a COX-2 inhibitor, which is a subtype of NSAIDs. Diclofenac is also an NSAID used for pain relief in arthritis, but naproxen is more commonly recognized in general practice due to its availability and efficacy as both an over-the-counter and prescription medication.

In summary, naproxen stands out as a first-line treatment option for managing arthritis pain and inflammation, making it the most suitable answer to the question regarding common drugs used for this condition.
