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-2 H -isoindol-2-yl) piperidine-2,6-dione and it has the following chemical structure: 3-(4-amino-1-oxo 1,3-dihydro-2 H -isoindol-2-yl) piperidine-2,6-dione 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. Freely soluble in dimethyl formamide, dimethyl sulphoxide, slightly soluble in acetone, methanol and practically insoluble in dichloromethane, n-Hexane, ethanol, chloroform and ethyl acetate. 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: anhydrous lactose, black iron oxide, croscarmellose sodium, gelatin, magnesium stearate, microcrystalline cellulose, potassium hydroxide, shellac and titanium dioxide. The 10 mg, 15 mg and 20 mg capsule shell contains iron oxide red. The 2.5 mg, 10 mg and 20 mg capsule shell contains iron oxide yellow. The 2.5 mg and 10 mg capsule shell contains FD&C blue 2.
