Abstract
Description
technical field
[0001] The invention relates to a sustained-release preparation and a preparation method thereof, in particular to a sustained-release tablet of an immunomodulator lenalidomide and a preparation method thereof. Background technique
[0002] Lenalidomide, chemical name 3-(7-amino-3-oxo-1H-isoindol-2-yl)piperidine-2,6-dione, molecular formula C 13 h 13 N 3 o 3 , its molecular weight is 259.2606, soluble in DMSO (100mg / ml), slightly soluble in methanol, ethanol, acetonitrile and water, it needs to be micronized, form strong acid salt or add solubilizer to improve its water solubility.
[0003] Lenalidomide is an antineoplastic drug developed by Celgene Biopharmaceutical Company of the United States for the treatment of myelodysplastic syndrome (MDS) and multiple myeloma (MM). It was approved by the FDA in 2005.
[0004] Lenalidomide is a representative drug of the new generation of immunomodulators, with a unique dual mechanism of action. On the one hand, l...
