Relafen is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs).Relafen is used to treat pain or inflammation caused by arthritis. Relafen works by reducing hormones that cause inflammation and pain in the body.RELAFEN (nabumetone) is a naphthylalkanone designated chemically as 4-(6-methoxy-2-naphthalenyl)-2-butanone. Nabumetone is a white to off-white crystalline substance with a molecular weight of 228.3. It is nonacidic and practically insoluble in water, but soluble in alcohol and most organic solvents. It has an n-octanol:phosphate buffer partition coefficient of 2400 at pH 7.4. The parent compound is a prodrug, which undergoes hepatic biotransformation to the active component, 6-methoxy-2-naphthylacetic acid (6MNA), that is a potent inhibitor of prostaglandin synthesis.



Relafen is acidic and has an n-octanol:phosphate buffer partition coefficient of 0.5 at pH 7.4.Free fraction is dependent on total concentration of 6MNA and is proportional to dose over the range of 1,000 mg to 2,000 mg. It is 0.2% to 0.3% at concentrationsNabumetone itself is not detected in the plasma. Approximately 35% of a 1,000-mg oral dose of nabumetone is converted to 6MNA and 50% is converted into unidentified metabolites which are subsequently excreted in the urine. 6MNA is more than 99% bound to plasma proteins. 6MNA exhibits pharmacokinetic characteristics that generally follow a one-compartment model with first order input and elimination.

Relafen medication should not be used certain medical conditions. Relafen cause stomach bleeding. Daily use of alcohol and tobacco, mostly when combined with this medicine, may increase your risk for stomach bleeding. Before using Relafen tell your doctor or pharmacist your medical history, especially of: kidney disease, liver disease and poorly controlled diabetes. Check all prescription and nonprescription medicine labels carefully since many contain pain relievers/fever reducers (NSAIDs such as aspirin, ibuprofen or naproxen), which are similar to this drug. Before using Relafen consult your doctor or pharmacist if you have: aspirin-sensitive asthma, recent heart bypass surgery.
