Abstract

The invention discloses dexibuprofen particles and a preparation method thereof. According to the invention, appropriate auxiliary materials are combined with dexibuprofen, such that dexibuprofen is subject to self-emulsification in gastrointestinal tracts, and is maintained an emulsion. Compared with common dexibuprofen preparations, the dexibuprofen particles provided by the invention has advantages of good dissolution rate, high absorption speed, good controllability of preparation technological quality, good stability, and the like. The invention provides a dexibuprofen preparation with higher security, better curative effect, simpler preparation technology and good stability.

Description

technical field [0001] The invention belongs to the field of pharmaceutical manufacturing, and relates to a new dosage form of ibuprofen, in particular to a granule of ibuprofen and a preparation method thereof. Background technique [0002] Dexibuprofen is the S-(+)-isomer of the widely used non-steroidal anti-inflammatory drug ibuprofen (racemate), which was launched in Austria in 1994 for the treatment of rheumatoid arthritis Inflammation, a racemic compound that is widely used clinically, its anti-inflammatory effect is produced by the S-isomer inhibiting the synthesis of prostaglandins. It has been clarified that the R-isomer is converted into its S-isomer through a coenzyme A thioester intermediate in vivo, and the formation of R-ibuprofen coenzyme A competitively inhibits many reactions that depend on coenzyme A, Thereby interfering with liver cell intermediary metabolism and mitochondrial function. Therefore, the advantages of using pure S-ibuprofen are mainly to r...
