Sunitinib is a kinase inhibitor present in sunitinib malate capsules as the malate salt. Sunitinib malate is described chemically as N-(2-(Diethylamino)ethyl)-5-((Z)-(5-fluoro-1,2-dihydro-2-oxo-3H-indol-3-ylidene)methyl)-2,4-dimethyl-1H-pyrrole-3-carboxamide (2S)-hydroxybutanedioate acid. The molecular formula is C 22 H 27 FN 4 O 2 • C 4 H 6 O 5 and the molecular weight is 532.6 g/mol. The chemical structure of sunitinib malate is: Sunitinib malate is a yellow or orange-yellow powder with a pKa of 8.95. The solubility of sunitinib malate is slightly soluble in water, practically insoluble in ethanol. Sunitinib malate capsules are supplied as printed hard-shell capsules containing 12.5 mg, 25 mg, 37.5 mg, and 50 mg of sunitinib (equivalent to 16.7 mg, 33.4 mg, 50.1 mg, and 66.8 mg of sunitinib malate, respectively). The capsules contain the following inactive ingredients: croscarmellose sodium, magnesium stearate, mannitol, and povidone. The orange gelatin capsule shells contain red iron oxide, and titanium dioxide; the caramel gelatin capsule shells contain black iron oxide, red iron oxide, titanium dioxide, and yellow iron oxide; and the yellow gelatin capsule shells contain titanium dioxide, and yellow iron oxide. The white printing ink contains potassium hydroxide, propylene glycol, shellac, and titanium dioxide and the black printing ink contains black iron oxide, potassium hydroxide, propylene glycol, and shellac. image description
