The safety of Arthrotec in patients with rheumatoid arthritis or osteoarthritis: an assessment of the upper gastrointestinal tract by endoscopy. [Clinical Trial, Journal Article, Randomized Controlled Trial]
Scand J Rheumatol Suppl 1992.:23-31.
Two double-blind comparative studies were conducted to determine the upper gastrointestinal safety of Arthrotec, a combination of 50 mg of diclofenac and 200 micrograms of misoprostol versus 50 mg of diclofenac. In one study, rheumatoid arthritis patients were randomly given Arthrotec or diclofenac 2 or 3 times daily for 12 weeks. Endoscopy was performed before and after treatment. At the termination of treatment, among the 290 patients with rheumatoid arthritis, gastroduodenal ulcers were found in 4% of the Arthrotec-treated patients and in 11% of the diclofenac-treated patients (P = 0.034). In the second study, osteoarthritis patients were randomly given Arthrotec or diclofenac 2 or 3 times daily for 4 weeks. Endoscopy was performed before and after treatment. Among the 329 patients with osteoarthritis, gastroduodenal ulcers were found in none of the Arthrotec patients and in 4% of the diclofenac patients (P = 0.015).
