How Diclofenak Works

Diclofenak works by inhibiting the action of certain enzymes in the body that contribute to inflammation. These enzymes are known as cyclooxygenase (COX) enzymes.

By blocking these enzymes, Diclofenak reduces the production of substances that cause pain and swelling.

This mechanism helps alleviate symptoms such as pain and discomfort associated with inflammatory conditions.
