Diclofenac
Diclofenac is a widely used and powerful Non-Steroidal Anti-Inflammatory Drug (NSAID) known for its potent analgesic and anti-inflammatory effects across multiple indications (oral, topical, injectable). It works by non-selectively inhibiting cyclooxygenase enzymes (COX-1 and COX-2), thereby blocking prostaglandin synthesis. This API is highly effective for managing conditions like acute pain, arthritis, and migraine attacks. Diclofenac is a mainstay in both musculoskeletal and acute pain management.
What is Diclofenac?
Diclofenac is a widely used anti-inflammatory medicine that helps reduce pain, swelling, and stiffness caused by various joint and muscle conditions. It is available in several forms including tablets, pills, gels, and topical solutions, making it suitable for both short-term and long-term pain relief. Doctors often prescribe this medicine for arthritis flare-ups, muscle injuries, and other painful inflammatory conditions. Its fast action and strong therapeutic effect make it a trusted option worldwide.

Chemical Composition
The active ingredient in this medicine is Diclofenac, which belongs to the NSAID (Non-Steroidal Anti-Inflammatory Drug) class. Depending on the formulation, it may appear as Diclofenac Sodium or Diclofenac Potassium. Topical versions may contain additional soothing agents to improve penetration through the skin.
Diclofenac Mechanism
Diclofenac works by blocking the action of prostaglandins—chemicals that trigger inflammation and pain. By reducing prostaglandin production, this medicine decreases swelling, eases discomfort, and improves mobility. Because of its dual action on inflammation and pain signals, many patients experience relief within a few hours of use.
