Description and Brand Names
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to manage pain and inflammation. It is available under various brand names such as Voltaren, Voltaren-XR, Zipsor, and Zorvolex. This medication is frequently used to treat inflammatory conditions like rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. Developed by Novartis, diclofenac sodium is widely used to alleviate symptoms of pain and inflammation. As an NSAID, diclofenac works by reducing pain and inflammation associated with various conditions affecting joints, muscles, and bones.
Mechanism of Action
Diclofenac, the active ingredient in medications like Voltaren, exerts its effects by inhibiting the enzyme cyclooxygenase (COX) involved in the synthesis of prostaglandins, which are mediators of pain and inflammation. By blocking this enzyme, diclofenac reduces the production of prostaglandins, thereby alleviating pain, swelling, and inflammation associated with various conditions such as arthritis. This mechanism of action makes diclofenac effective in managing inflammatory conditions and providing relief from pain.
Indications
Diclofenac, marketed under brand names like Voltaren, is commonly indicated for the management of mild to moderate pain and inflammatory conditions. This medication is frequently prescribed to alleviate symptoms associated with inflammatory disorders such as rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis.
