Nabumetonealcohol is the alcohol form of nabumetone, a non-steroidal anti-inflammatory drug (NSAID) that is rapidly metabolized in the liver to a major active metabolite, 6-methoxy-2-naphthyl acetic acid, which inhibits the cyclooxygenase enzyme and preferentially blocks COX-2 activity (which is indirectly responsible for the production of inflammation and pain during arthritis).
