Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and relates to an acrylic non-steroidal anti-inflammatory drug dexketoprofen tromethamine gel plaster and a preparation method thereof. Background technique [0002] Ketoprofen is an acrylic non-steroidal anti-inflammatory drug, mainly used for the treatment of rheumatic or rheumatoid arthritis, osteoarthritis, ankylosing spondylitis and postoperative pain. The structural formula of ketoprofen has a chiral carbon atom, and the drug has been generally used in the form of racemate for a long time. It has been found through research that the L-form of ketoprofen is almost inactive, while the anti-inflammatory effect of the D-form is twice that of the racemic form of ketoprofen. However, dexketoprofen has low solubility and poor absorption, so it is often used as tromethamine salt. [0003] Dexketoprofen trometamol tablets were first developed by The Menarini Group and first lau...
