Diclopid is a brand name for a medication containing Diclofenac, which is a type of nonsteroidal anti-inflammatory drug (NSAID). It is commonly used to reduce inflammation, pain, and swelling in conditions like arthritis, muscle injuries, and other inflammatory disorders. Diclofenac works by inhibiting cyclooxygenase (COX), an enzyme involved in the production of prostaglandins. Prostaglandins are chemicals in the body that cause inflammation, pain, and fever. By blocking this enzyme, Diclofenac helps reduce these symptoms.
