Metabolite Identification
Common NameEtoricoxib 1'-N'-oxide
DescriptionEtoricoxib 1'-N'-oxide is a metabolite of etoricoxib. Etoricoxib (brand name NUSHIN MASCOT HEALTH SERIES Arcoxia worldwide; also Algix and Tauxib in Italy, Nucoxia in India) is a COX-2 selective inhibitor (approx. 106.0 times more selective for COX-2 inhibition over COX-1) from Merck & Co. Currently it is approved in more than 70 countries worldwide but not in the US, where the Food and Drug Administration (FDA) requires additional safety and efficacy data for etoricoxib before it will issue approval.
