摘要: The present invention discloses an ibuprofen amine salt and the synthesis thereof, and more particularly an ibuprofen amine salt yielded by the neutralization reaction of a racemic mixture of ibuprofen with tris(hydroxymethyl)aminomethane in a solution system of water and an organic solvent. Compared with racemic mixtures of ibuprofen, the ibuprofen amine salt has higher solubility and a higher melting point, thereby having better bioavailability and properties than racemic mixtures of ibuprofen during pharmaceutical processing. Further, the ibuprofen amine salts of the present invention are stable between pH 4 and 9 so that they can be more widely applied to medicines.
