How Does Diclofenac Work?
Like other NSAIDs, diclofenac works by blocking a specific enzyme known as cyclooxygenase (COX), blocking the production of various inflammatory substances in the body. This action helps to treat pain and inflammation but also seems to help treat seemingly unrelated conditions (such as actinic keratosis).
