Abstract

The invention provides a dexibuprofen medical composition that can improve dissolution and a preparation method thereof, relating to the method technology field that improves the dissolution rate of the dexibuprofen medical compositions which comprise amino acid, sodium carbonate and sodium bicarbonate, being added with proper amount of other pharmaceutic adjuvant to form a new dexibuprofen medical composition. The dexibuprofen medical composition added with solubilization composition can be dissolved quickly in vivo and in vitro to shorten the absorption time and to improve the bioavailability of the blood plasma, thus resisting disease more quickly and effectively.

Description

technical field [0001] The invention provides a dexibuprofen pharmaceutical composition with improved dissolution performance and a preparation method thereof, and relates to the technical field of methods for improving the dissolution rate of dexibuprofen medicine. 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. It is a non-steroidal antipyretic and analgesic drug, mainly used for the treatment of fever and pain induced by acute upper respiratory tract infection in children, acute pharyngitis and other diseases, various types of rheumatoid arthritis, rheumatoid arthritis, gout, various muscle injury pains, Acute mild to moderate pain, fever, etc. [0003] Studies have shown that there are great differences in the efficacy of ibuprofen chiral enantiomers, and the activity of dextroibuprofen is 160 times that of L-isomer and 1.6 times that of ra...
