NCIt definition : A naphthylalkanone and non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory,
antipyretic and analgesic activities. Nabumetone is a prodrug that upon hepatic catalysis
converts into the active moiety 6-methoxy-2-naphthylacetic acid (6MNA). 6MNA inhibits
the activity of the enzymes cyclo-oxygenase I and II, resulting in decreased formation
of precursors of prostaglandins and thromboxanes. The resulting decrease in prostaglandin
synthesis is responsible for the therapeutic effects of nabumetone. The formation
of thromboxane A2, by thromboxane synthase, is also decreased and results in an inhibition
of platelet aggregation.;
