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- 2H -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 259.26 g/mol. Lenalidomide is an off-white to pale-yellow powder. It is freely soluble in dimethylsulfoxide, slightly soluble in acetonitrile and methanol, very slightly soluble in ethyl acetate, and practically insoluble, or insoluble in water, absolute ethanol, hexane and isopropanol. 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 crystalline anhydrous lenalidomide as the active ingredient and the following inactive ingredients: anhydrous lactose, croscarmellose sodium, magnesium stearate and microcrystalline cellulose. The 5 mg and 25 mg capsule shell contains gelatin, titanium dioxide and black ink. The 2.5 mg, 10 mg and 20 mg capsule shell contains FD&C blue #2, gelatin, iron oxide yellow, titanium dioxide and black ink. The 15 mg capsule shell contains FD&C blue #2, gelatin, titanium dioxide and black ink. The capsule imprinting black ink contains ammonium hydroxide 28%, iron oxide black, propylene glycol and shellac.
