Dexibuprofen

Dexibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) used for its analgesic, anti-inflammatory, and antipyretic properties. It is the dextral or right-handed enantiomer of ibuprofen, which means it is one of the two mirror-image forms of the molecule. Dexibuprofen is considered to be more potent and to have fewer side effects compared to racemic ibuprofen, which contains both the dextrorotatory and levorotatory enantiomers.

Pharmacology

Dexibuprofen works by inhibiting the cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. These enzymes are involved in the synthesis of prostaglandins, which are mediators of inflammation, pain, and fever. By reducing the production of prostaglandins, dexibuprofen helps to alleviate symptoms associated with inflammatory conditions.
