'fountain of youth' pill - lenalidomide is a derivative of thalidomide

[Guest guest]

Lenalidomide (pronounced /lɛnəˈlɪdɵmaɪd/), initially known as CC-5013 and marketed as Revlimid by Celgene, is a derivative of thalidomide introduced in 2004. It was initially intended as a treatment for multiple myeloma, for which thalidomide is an accepted therapeutic treatment. Lenalidomide has also shown efficacy in the class of hematological disorders known as myelodysplastic syndromes (MDS). Lenalidomide and bortezomib are considered therapeutic breakthroughs in the treatment of myeloma, which generally carries a poor prognosis
