Use of Etodolac

Etodolac is a non-steroidal anti-inflammatory compound that is a non-selective inhibitor of COX (IC50=53.5 nM)IC50 value: 53.5 nMTarget: COX1; COX2Post-marketing studies demonstrated that etodolac inhibition of cyclooxygenase is somewhat COX-2 selective similar to celecoxib and other "COX-2 inhibitors." Unlike rofecoxib, both etodolac and celecoxib can fully inhibit COX-1 and are designated as having "preferential selectivity" toward COX-2. The (inactive against COX) r-enantiomer of etodolac inhibits beta-catenin levels in hepatoma cells.
