Rheumatoid arthritis affects about 1% of the population worldwide, but still misunderstanding swirls around this common and severe joint condition.
"There are so many misconceptions out there about rheumatoid arthritis," says Paul Kremer, MD, a rheumatologist and professor of medicine at Albany Medical College in New York.
"Arthritis is common, and rheumatoid arthritis often gets confused with the other kinds of arthritis in people's minds,” he says.
Plus, rheumatoid arthritis is still mysterious...
When you have pain from rheumatoid arthritis, the damaged tissue releases chemicals called prostaglandins, which are like hormones.
Prostaglandins send messages to trigger inflammation that results in pain and swelling. NSAIDs block prostaglandins by blocking Cox enzymes (specifically, Cox-1 and Cox-2 enzymes). This decreases inflammation and reduces pain and stiffness.
While prostaglandins trigger inflammation, they also send a few good messages as well, for example, protecting the stomach lining and kidneys. By blocking prostaglandins entirely, NSAIDs can sometimes cause stomach ulcers, bleeding, and even kidney damage.
NSAIDs vary in their strength and likelihood of causing side effects. It seems the more an NSAID blocks the Cox-1 enzyme, the greater the tendency is to cause stomach ulcers and promote bleeding.
What Are Some NSAIDS Used for Rheumatoid Arthritis?
Aspirin (Bufferin, Bayer)
Diclofenac (Cataflam, Voltaren)
Ibuprofen (Advil, Motrin)
Ketoprofen (Oruvail, Orudis)
Naproxen (Aleve, Anaprox, Naprelan, Naprosyn)
Arthrotec is an NSAID that combines diclofenac with another active ingredient, misoprostol, to help prevent stomach irritation.
Prevacid Naprapac combines naproxen with the acid blocker Prevacid to reduce the chance of developing stomach ulcers. Vimovo is a combination of naproxen and the acid blocker Nexium.
What Is a Cox-2 Inhibitor?
Cox-2 inhibitors are a newer form of prescription NSAID and work similarly to older NSAIDs. However, Cox-2 inhibitors are less likely to cause stomach problems, such as ulcers.
Cox-2 inhibitors offer the same pain relief as standard NSAIDs but have a lower risk of stomach problems.
Celebrex is the only Cox-2 inhibitor.
Do All NSAIDs Increase Risk of Heart Attack and Stroke?
All prescription NSAIDs are linked to an increased risk of heart attack and stroke.
