Description

technical field [0001] The invention relates to a flurbiprofen axetil injection dosage form and a preparation method thereof. Background technique [0002] Flurbiprofen axetil (Flurbrofene axetil) is the acetoxyethyl ester of flurbiprofen, which can be hydrolyzed by carboxyl esterase in vivo to produce flurbiprofen, which inhibits the synthesis of prostaglandins. Flurbiprofen is a non-steroidal anti-inflammatory drug (NSAID) widely used clinically. It has anti-inflammatory, analgesic and antipyretic effects, and is clinically used for the treatment of pain or inflammatory diseases.
