Lenalidomide capsules, a thalidomide analogue, are 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: The molecular formula for lenalidomide is C 13 H 13 N 3 O 3 , and the gram molecular weight is 259.27. Lenalidomide is an off-white to pale yellow powder. It is soluble in organic solvent/water mixtures, and buffered aqueous solvents. Lenalidomide is more soluble in organic solvents and low pH solutions. Solubility was significantly lower in less acidic buffers, ranging from about 0.4 to 0.5 mg/mL. 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: colloidal silicon dioxide, croscarmellose sodium, gelatin, microcrystalline cellulose, pregelatinized starch (corn), sodium stearyl fumarate and titanium dioxide. The 2.5 mg, 10 mg and 20 mg capsules also contain FD&C Blue No. 2 and yellow iron oxide. The 10 mg capsules also contain black iron oxide. The black imprinting ink for the 2.5 mg, 5 mg, 10 mg and 25 mg capsules contains black iron oxide, potassium hydroxide, propylene glycol, shellac and strong ammonia solution. The red imprinting ink for the 15 mg and 20 mg capsules contains ammonium hydroxide, propylene glycol, red iron oxide, shellac glaze and simethicone. Lenalidomide Structural Formula
