4. Uses of Lenalidomide
Lenalidomide (CAS NO.191732-72-6) is used for immunomodulatory drug, analog of THALIDOMIDE. It was initially intended as a treatment for multiple myeloma, for which thalidomide is an accepted therapeutic modality, but has also shown efficacy in the hematological disorders known as the myelodysplastic syndromes.
