Similar to other NSAIDs, Ketorolac works by blocking the production of prostaglandins, substances in the body that cause pain and inflammation. By inhibiting the action of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, Ketorolac interferes with the release of prostaglandins, thus providing analgesic and anti-inflammatory effects.
Due to its potent pain relief capabilities and potential side effects, Ketorolac is usually only recommended for short-term use (up to 5 days for adults).
