Abstract

The invention relates to a pharmaceutical composition containing lenalidomide, and a preparation method thereof. The pharmaceutical composition is prepared from the lenalidomide, a thinning agent, a disintegrating agent, a lubricating agent and an optional pharmaceutically acceptable carrier. The pharmaceutical composition containing the lenalidomide provided by the invention has favorable stability and drug dissolution rate, the product quality can be controlled, and the preparation method is simple in process, high in operability and suitable for industrialized mass production.

Description

technical field [0001] The invention belongs to pharmaceutical preparations, in particular to a pharmaceutical preparation of lenalidomide and a preparation method thereof. Background technique [0002] Lenalidomide (Revlimid), the chemical name is 3-(4-amino-1,3-dihydro-1-oxo-2H-isoindol-2-yl)-2,6-piperidine di Ketone, formula C 13 h 13 N 3 o 3 , and its molecular weight is 259.2606. Lenalidomide is an antineoplastic drug developed by Celgene Biopharmaceutical Company of the United States. It is an analogue of thalidomide, but it has fewer side effects than thalidomide and does not cause neonatal deformities. Clinically, it is mainly used for the treatment of myelodysplastic syndrome (MDS), multiple myeloma (MM), leukemia and mantle cell lymphoma, and was approved by the FDA in 2005. Lenalidomide is a representative drug of a new generation of immunomodulators, which has a dual mechanism of action. [0003] The patent No. US7119106 provides a pharmaceutical compositi...
