Abstract

The invention provides dexketoprofen trometamol injection and a technology for preparing the same. The dexketoprofen trometamol injection and the technology have the advantages that phosphate is usedas a stabilizer, accordingly, the problem that effective components are easy to degrade in common dexketoprofen trometamol injection production procedures can be solved by the aid of the dexketoprofentrometamol injection and the technology, the dexketoprofen trometamol injection is stable in quality, good in clarity, easy and convenient to operate and suitable for industrial mass production, andtechnological processes are simple.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a dexketoprofen tromethamine injection and a preparation process thereof. Background technique [0002] Dexketoprofen trometamol is a derivative of dexketoprofen, a single optical isomer of 2-arylpropionic acid non-steroidal anti-inflammatory drugs (NASIDs) ketoprofen, which has a strong antipyretic effect , analgesic and anti-inflammatory effects, better water solubility than dexketoprofen, higher activity than free acid, high bioavailability, and better tolerance to patients, so it has broad clinical application prospects. Clinically applicable to mild to moderate pain of different causes, such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, joint pain of gouty arthritis, dysmenorrhea, toothache, postoperative pain, cancer pain, acute All kinds of acute and chronic pains such as sprain or soft tissue contusion pain, general pain caused by cold and...
