Mechanism of action

By selectively inhibiting COX-2, ATB-346 low dose aims to reduce inflammation and pain while minimizing the risk of gastrointestinal side effects associated with traditional NSAIDs. This is achieved through a proprietary prodrug that is rapidly converted to its active form, allowing for targeted COX-2 inhibition.
