Flosulide is primarily used as a nonsteroidal anti-inflammatory drug (NSAID) with potent anti-inflammatory, analgesic, and antipyretic properties. It is commonly applied in the treatment of inflammatory conditions such as arthritis, including rheumatoid arthritis and osteoarthritis, to reduce pain, swelling, and stiffness in the joints. Its mechanism involves the inhibition of cyclooxygenase (COX) enzymes, which are responsible for the production of prostaglandins that mediate inflammation and pain. Flosulide is also explored in research for its potential therapeutic effects in other inflammatory disorders and conditions where inflammation plays a key role. Due to its selective action, it may offer a favorable safety profile compared to non-selective NSAIDs, particularly in terms of gastrointestinal side effects.
