Arthrotec contains a combination of diclofenac and misoprostol. Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing substances in the body that cause pain and inflammation. Misoprostol reduces stomach acid and replaces protective substances in the stomach that are reduced by NSAIDs. Arthrotec is used to treat osteoarthritis and rheumatoid arthritis in people at high risk for developing stomach or intestinal ulcers.
