Description and Uses
Aqueous solutions of indomethacin are not stable because of the ease of hydrolysis of the p-chlorobenzoyl group. The original synthesis of indomethacin by Shen et al. involved the formation of 2-methyl-5-methoxyindole acetic acid and subsequent acylation after protection of the carboxyl group as the t-butyl ester. It was introduced in the United States in 1965. It is still one of the most potent NSAIDs in use. It also is a more potent antipyretic than either aspirin or acetaminophen, and it possesses approximately 10 times the analgetic potency of aspirin.
Indomethacin is used in rheumatoid arthritis, nonspecific infectious polyarthritis, gouty arthritis, osteoarthritis, ankylosing spondylitis, arthrosis, back pain, neuralgia, myalgia, and other diseases accompanied by inflammation.
