Ketorolac trometamol works by blocking the action of a substance in the body called cyclo-oxygenase (COX). Cyclo-oxygenase is involved in producing prostaglandins, in response to injury or certain diseases, such as arthritis. These prostaglandins cause pain, swelling and inflammation. Ketorolac trometamol blocks the production of these prostaglandins and so is effective at relieving pain and inflammation.

Acular eye drops are used to treat pain and swelling after eye surgery.
