Diclofenac belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs) [1]. It works by blocking enzymes called cyclooxygenases (COX), which are involved in the production of prostaglandins. Prostaglandins are substances that contribute to inflammation, pain, and fever [1]. By inhibiting COX, diclofenac reduces the levels of prostaglandins, thereby alleviating these symptoms.
