Mechanism of action

Etoricoxib belongs to a group of medicines called Coxibs or COX-2 inhibitors. It works similarly as most traditional anti-inflammatory drugs classified as NSAID (Non-Steroidal Anti-Inflammatory Drugs) by blocking the action or production of certain substances known to cause inflammation or pain. It inhibits isoform 2 produced in the COX-2 (cyclo-oxigenase) enzyme and reduces the production of PG (Prostaglandins) from archidonic acid. It selectively inhibits COX-2 more significantly than COX-1 enzymes that traditional NSAID non-selectively inhibits and accounts for its diminished sided effects in the gastrointestinal tract. In several clinical tests, the brand Arcoxia has shown fewer risks to side effects such as bleeding stomach ulcers) than using NSAIDs. However, it should be noted that its benefits are reversed when taking Aspirin with it.
