There are so many over-the-counter and prescription medicines available to treat pain that it can be difficult to select the best one. A group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat mild to moderate pain. In this article, we will compare two medications — diclofenac and ibuprofen. Both are NSAIDs and are frequently used by patients with arthritis and other illnesses subjected to chronic pain with no evidence of renal impairment.

What are nonsteroidal anti-inflammatory drugs? How do they work?

Nonsteroidal anti-inflammatory drugs (NSAIDs) are used for treating pain and reducing inflammation. They work by reducing hormones called prostaglandins which play a critical role in the body by eliciting a pain response and causing inflammation.

A nonsteroidal anti-inflammatory drug can either be selective for COX-1 or COX-2 enzyme, thereby blocking a portion of prostaglandin synthesis or nonselective by blocking both COX-1 and COX-2, thereby diminishing prostaglandin synthesis to an even greater degree. Why not always block prostaglandin synthesis? Well, prostaglandins also help dilate blood vessels, which is important for organs, particularly the kidneys. This is why variety is so appreciated when dealing with complex patients.

Both diclofenac and ibuprofen are non-selective NSAIDs, meaning they block both COX-1 and COX-2 enzymes. Therefore, these drugs work in the same way.

Notably, COX-1 protects the stomach lining, so when you block this enzyme with drugs like diclofenac and ibuprofen, it can lead to gastrointestinal symptoms such as stomach pains, ulcers, etc.

What is diclofenac?

Diclofenac is an FDA-approved prescription NSAID used to treat rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis in adults since these diseases at their foundation are caused by inflammatory processes.

What is ibuprofen?

Ibuprofen is a nonsteroidal anti-inflammatory drug that can be purchased over the counter and is also available by prescription. Over-the-counter ibuprofen is used to treat fever and minor aches and pains in children and adults, such as headache, muscle ache, backache, toothache, and menstrual pain. Ibuprofen prescription strength is used to treat arthritic pain and inflammation in adults.

Are diclofenac and ibuprofen the same?

No, diclofenac and ibuprofen are not the same medication. They are both nonsteroidal anti-inflammatory drugs, but there are some key differences between them.

This is not a complete list of drug interactions between NSAIDs and other drugs. Always talk to a doctor or pharmacist before taking an NSAID if you take other medications.

Warnings

Diclofenac vs. ibuprofen: Which is better?

Diclofenac is a more potent NSAID than ibuprofen. Taking diclofenac 2-3 times daily can effectively treat arthritis pain. To treat joint pain with ibuprofen, a higher dose such as a “prescription-strength dose” is usually needed.

Is diclofenac or ibuprofen more effective?

A meta-analysis of 176 studies and 146,524 patients published in the Journal of Arthritis Research and Therapy found that diclofenac 150 mg/day is more effective than ibuprofen 2,400 mg/day for arthritis pain relief.

The study also showed that diclofenac is a better choice than other drugs like naproxen 1,000 mg/day and celecoxib 200 mg/day, which are also nonsteroidal anti-inflammatory drugs.

Moreover, the risk of stomach-related side effects was found to be lower with diclofenac when compared to ibuprofen.

Nevertheless, both diclofenac and ibuprofen are effective medications when used at the appropriate doses. Plenty of considerations, such as drug cost, mechanism of action, patient disease profile, etc., go into the decision-making of what medication works best for you, so you should obtain professional medical advice from a healthcare provider to determine which drug is most beneficial for you.
