Etodolac vs Meloxicam

Etodolac vs Meloxicam:


COX-2 inhibitors are NSAIDs (nonsteroidal anti-inflammatory drugs) that selectively block the COX-2 enzyme and not the COX-1 enzyme (an enzyme that helps with the production of the protective stomach lining).

Because they selectively block the COX-2 enzyme and not the COX-1 enzyme, these nonsteroidal anti-inflammatory drugs are uniquely different from traditional NSAIDs that commonly block both COX-1 and COX-2 enzymes.

COX-2 is an enzyme responsible for inflammation and pain and is constitutively expressed in the kidney, in the brain, in bone, and in the female reproductive system.

COX-2 Selective NSAIDs are used for treating:

  • rheumatoid arthritis;
  • ankylosing spondylitis;
  • acute pain (for instance, sports injuries);
  • menstrual cramps;
  • osteoarthritis;
  • juvenile rheumatoid arthritis.

COX-2 selective nonsteroidal anti-inflammatory drugs are associated with fewer gastrointestinal adverse effects than nonselective NSAIDs. According to research, the absolute risk of serious upper gastrointestinal bleeding and ulceration is reduced by 50 to 60 percent or more compared to other nonsteroidal anti-inflammatory drugs.

But, the improved tolerance of the COX-2 selective inhibitors may possess an increased risk of thrombosis in people with ischaemic heart disease, especially if they are not taking aspirin.

Here is a comparison between Etodolac and Meloxicam, two types of COX-2 inhibitors:


It is a member of the pyranocarboxylic acid class of NSAIDs and is approved by the US FDA for treating acute pain in adults.


Meloxicam is a nonsteroidal anti-inflammatory drug that is only available with a prescription.

The Food and Drug Administration approved it for use in the United States in 2000.


Etodolac is prescribed for the treatment of pain and inflammation associated with rheumatoid arthritis, osteoarthritis, tendinitis, bursitis, juvenile rheumatoid arthritis, and menstrual cramps.

Also, it may be used for the relief of:

  • pain or inflammation caused by knee pain, back pain, or foot pain;
  • symptoms of systemic lupus erythematosus;
  • gout symptoms;
  • fibromyalgia symptoms.

Meloxicam eases pain and swelling in long-term conditions such as ankylosing spondylitis and rheumatoid arthritis.

Additionally, it may be prescribed for a shorter period of time in osteoarthritis.

Mechanism of Action

Etodolac works by blocking the enzyme which makes prostaglandins. This leads to a lower concentration of prostaglandins.

Meloxicam works by blocking lipids which are involved in the body’s response to perceived injury, leading to blood clotting and inflammation around the wound site.

The drug has a half-life of 20 to 24 hours and a bioavailability of 89 percent after oral intake.

Etodolac vs Meloxicam – Which Is Better?

Etodolac is a nonsteroidal anti-inflammatory drug approved in the US for the treatment of acute pain and for managing the symptoms of osteoarthritis and rheumatoid arthritis.

It works by blocking the effect of cyclo-oxygenase (COX) enzymes, natural substances in the human body.

Meloxicam is an enolcarboxamide with preferential COX-2 inhibitory activity. It is prescribed for the treatment of joint inflammation and pain, usually from osteoarthritis or rheumatoid arthritis.

According to a 2008 review of the cost-effectiveness and clinical effectiveness of cyclooxygenase-2 selective non-steroidal anti-inflammatory drugs, meloxicam and etodolac were found to be similar to non-selective nonsteroidal anti-inflammatory drugs for the symptomatic relief of rheumatoid arthritis and osteoarthritis.
