Lenalidomide is an anti-cancer medication used for the treatment of multiple myeloma and myelodysplastic syndrome. It is available in both capsule and tablet forms, with strengths of 5mg and 10mg, respectively. The medication functions by inhibiting the growth of blood vessels that supply nutrients to cancerous cells through anti-angiogenesis. Lenalidomide exhibits properties such as stopping the division and multiplication of cancerous cells (Cell-proliferation), preventing the development of chemicals used for cell communication, determining immune system function (Immunomodulatory effects), altering the production of cytokines crucial for cancer cell development and survival (Antineoplastic), and influencing genes controlling self-destruction and metabolism (apoptosis).
