Used primarily as an anti-inflammatory and analgesic agent in the treatment of rheumatoid arthritis, osteoarthritis, and other inflammatory joint conditions. It helps reduce pain, swelling, and stiffness in the joints. Also prescribed for short-term management of mild to moderate pain, including menstrual pain (dysmenorrhea), due to its ability to inhibit prostaglandin synthesis. Its sodium salt form improves solubility, aiding in faster absorption and onset of action when administered orally.
