Nabumetone is a nonsteroidal anti-inflammatory drug (NSAID). Nabumetone has been developed by Beecham. It is available under numerous brand names, such as Relafen, Relifex, and Gambaran. Nabumetone is a nonacidic NSAID that is rapidly metabolized in the liver to a major active metabolite, 6-methoxy-2-naphthyl acetic acid. As found with previous NSAIDs, nabumetone's active metabolite inhibits the cyclooxygenase enzyme and preferentially blocks COX-2 activity (which is indirectly responsible for the production of inflammation and pain during arthritis). The active metabolite of nabumetone is felt to be the compound primarily responsible for therapeutic effect. Comparatively, the parent drug is a poor inhibitor of COX-2 byproducts, particularly prostaglandins. It may be less nephrotoxic than indomethacin. There are two known polymorphs of the compound.Nabumetone has little effect on renal prostaglandin secretion and less of an association with heart failure than other traditional drugs of the class. Effects of nabumetone on blood pressure control in hypertensive patients on ACE inhibitors is also good—equivalent to paracetamol. As of 2015 the cost for a typical month of medication in the United States is 25 to US$50.
