Indomethacin was the product of a laboratory search for drugs with antiinflammatory properties. It was introduced in 1963 for the treatment of rheumatoid arthritis and related disorders. It is a nonselective COX inhibitor. Although indomethacin still is used clinically and is effective, toxicity and the availability of safer alternatives have limited its use. Sulindac was developed in an attempt to find a less toxic, but effective, congener of indomethacin and also is a nonselective COX inhibitor.
