Diclofenac is classified as a nonsteroidal anti-inflammatory drug (NSAID) [1].
What is the mechanism of action for diclofenac?
Diclofenac works by inhibiting cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. This inhibition reduces the production of prostaglandins, which are key mediators of inflammation, pain, and fever [2].
What conditions is diclofenac used to treat?
Diclofenac is prescribed to manage pain and inflammation associated with various conditions, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gout attacks [2]. It is also used for short-term treatment of moderate to severe pain [2].
What are the potential side effects of diclofenac?
Like other NSAIDs, diclofenac can cause gastrointestinal issues such as stomach pain, nausea, ulcers, and bleeding. It may also increase the risk of cardiovascular events like heart attack and stroke, particularly with long-term use or in individuals with existing heart conditions. Other potential side effects include kidney problems, high blood pressure, dizziness, and skin reactions [2][3].
How does diclofenac compare to other NSAIDs?
Diclofenac is considered a potent NSAID. Its efficacy in pain and inflammation management is comparable to other widely used NSAIDs. However, the risk profile, particularly for gastrointestinal and cardiovascular adverse events, can vary among different NSAIDs and individual patient factors [2][3].
When do patents for diclofenac expire?
The original patents for diclofenac have long since expired, allowing for the widespread availability of generic versions [4]. Information on specific patents related to newer formulations or delivery methods of diclofenac can be found on resources like DrugPatentWatch.com [4].
