Learn about our Medical Expert Board Print Arthrotec is a nonsteroidal anti-inflammatory drug (NSAID). Drugs classified as NSAIDs work by inhibiting the production of prostaglandins. Drugs classified as NSAIDs have anti-inflammatory, analgesic, and antipyretic properties. Lisa J. Goodman / Moment Mobile / Getty Images Overview Arthrotec is a combination drug of diclofenac and misoprostol. Diclofenac blocks COX-1 and COX-2 enzymes which produce prostaglandins and play a role in the inflammatory process. COX-1 also is involved in platelet function and stomach protection. Diclofenac is the nonsteroidal anti-inflammatory (NSAID) portion of Arthrotec. Misoprostol (a synthetic prostaglandin) protects the lining of the stomach by reducing acid production and stimulates the secretion of mucus in the gastrointestinal tract.
