Treatment Summary
Nabumetone is a non-steroidal anti-inflammatory drug (NSAID) used to reduce pain, swelling, and inflammation. While it doesn't usually irritate the stomach as much as other NSAIDs, it can still cause some stomach side effects. Nabumetone works by blocking an enzyme that helps create inflammation in the body. It was developed by Smithkline Beecham and was approved by the FDA in 1991.

Effectiveness
How Relafen Affects Patients
Nabumetone is a type of painkiller called a NSAID. It works by reducing inflammation and blocking chemicals that cause pain. This can help to reduce both mild-moderate acute and chronic pain, though it is not as effective for neuropathic pain. NSAIDs also reduce fever and can prevent further damage and inflammation from the immune system. However, taking NSAIDs long-term can lead to issues with the kidneys, stomach, and an increased risk of thrombosis.
How Relafen works in the body
Nabumetone works by blocking two enzymes, COX-1 and COX-2, from converting arachidonic acid into prostanoids. Prostanoids help to reduce pain, inflammation, and fever. They also help to protect the gastrointestinal tract and regulate blood flow in the kidneys. When nabumetone blocks these enzymes, it reduces the amount of prostanoids being produced. This can lead to an increase in inflammation and pain, as well as a decrease in gastrointestinal protection and kidney function. It can also lead to an imbalance between prostanoids and thromboxane, which can increase the risk of th
