What is Arcoxia? 

Arcoxia is a medication that belongs to a group of Non-steroidal anti-inflammatory drugs (NSAIDs) called selective COX-2 inhibitors, which are used to relieve pain and inflammation. Its active ingredient is etoricoxib, which specifically targets the cyclooxygenase-2 (COX-2) enzyme involved in inflammatory processes. 

Arcoxia's selective inhibition of the COX-2 enzyme has the advantage of lessened gastric side-effects e.g. gastritis, ulceration compared to older non-selective NSAIDs.
