Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) that has been widely used for several decades to treat various conditions, including arthritis, gout, and pain. As a potent inhibitor of prostaglandin synthesis, indomethacin has been shown to be effective in reducing inflammation and relieving pain. However, like all medications, it is not without its side effects and potential risks. In this article, we will provide an in-depth look at the uses, side effects, and more of indomethacin, exploring its therapeutic applications, potential complications, and essential considerations for patients and healthcare providers.
Indomethacin was first approved by the US Food and Drug Administration (FDA) in 1965 and has since become a widely used medication for various inflammatory and painful conditions. Its mechanism of action involves the inhibition of cyclooxygenase (COX) enzymes, which play a crucial role in the production of prostaglandins, hormone-like substances that mediate inflammation and pain. By blocking COX enzymes, indomethacin reduces prostaglandin synthesis, thereby decreasing inflammation and relieving pain.
