Abstract

The invention provides a transdermal patch containing diclofenac epolamine and its preparation method. The transdermal patch contains the following ingredients (by weight): 0.5-5.0% (preferably 1.3%) of diclofenac epolamine which is used as a main active ingredient, 1-10% of a skeleton agent, 15-25% of a wetting agent, 0-0.5% of a complexing agent, 0-10% of an adhesive, 0-1% of a whitening agent, 0-1% of a skin penetration enhancer, 0-1% of a bacteriostat, 0-1% of a crosslinking regulator, etc. and the rest of purified water. in the preparation, dihydroxyaluminium aminoacetate is selected as the crosslinking regulator, and ethylparaben is selected as the bacteriostat. The diclofenac epolamine transdermal patch prepared by the technology has more stable quality, is convenient to use, has a simple preparation process and is suitable for large-scale production.

Description

technical field [0001] The invention relates to a diclofenac eporamide transdermal patch and a preparation method thereof, belonging to the technical field of medicinal chemistry. Background technique [0002] The chemical name of diclofenac eporamide is 2-[(2,6-dichlorophenyl)amino]phenylacetic acid 2-pyrrolidine ethanolate, and the molecular formula is C 20 h 24 Cl 2 N 2 o 3 , the molecular weight is 411.3, and the structural formula is: [0003] [0004] Diclofenac Eporamide Patch was developed by the Swiss company IBSA and launched in the United States in 2008. [0005] Diclofenac eporamide is a non-steroidal anti-inflammatory drug (NSAIDs), and its active ingredient diclofenac is a derivative of phenylacetic acid, which has significant analgesic and anti-inflammatory effects. Diclofenac inhibits the biosynthesis of prostaglandins, which are major contributors to inflammation, pain, and fever. [0006] Diclofenac Eporamide can be used to relieve mild to moderat...
