Lenalidomide, a thalidomide analogue, is an immunomodulatory agent with antiangiogenic and antineoplastic properties. The chemical name is 3-(4-amino-1-oxo 1,3- dihydro-2H-isoindol-2-yl) piperidine-2,6-dione and it has the following molecular structure: The molecular formula for lenalidomide is C 13 H 13 N 3 O 3 , and the gram molecular weight is 259.3. Lenalidomide is an off white to pale yellow powder. It is slightly soluble in methanol, acetonitrile and 0.1N hydrochloric solution. Lenalidomide has an asymmetric carbon atom and can exist as the optically active forms S(-) and R(+), and is produced as a racemic mixture with a net optical rotation of zero. Lenalidomide is available in 2.5 mg, 5 mg, 10 mg, 15 mg, 20 mg and 25 mg capsules for oral administration. Each capsule contains lenalidomide as the active ingredient and the following inactive ingredients: croscarmellose sodium, lactose monohydrate, magnesium stearate and microcrystalline cellulose. The capsule shell for all the strengths contains gelatin and titanium dioxide. The green imprinting ink contains FD&C Blue # 2 Aluminum Lake, ferric oxide yellow, propylene glycol, shellac, strong ammonia solution, and titanium dioxide (2.5 mg, 10 mg and 20 mg). The black imprinting ink contains ferrosoferric oxide, potassium hydroxide, propylene glycol, shellac, and strong ammonia solution (5 mg and 25 mg). The blue imprinting ink contains FD&C Blue# 2 Aluminum Lake, propylene glycol, shellac, and strong ammonia solution (15 mg and 20 mg). The yellow imprinting ink contains ferric oxide yellow, propylene glycol, shellac, and strong ammonia solution (10 mg). spl-lenalidomide-structure
