Sunitinib is a kinase inhibitor present in sunitinib malate capsules as the malate salt. Sunitinib malate is described chemically as (2S)-2-hydroxybutanedoic acid with N-[2-(diethylamino)ethyl]-5-[(Z)-(5-fluoro-1,2-dihydro-2-oxo-3H-indol-3-ylidine)methyl]-2,4-dimethyl-1H-pyrrole-3-carboxamide (1:1). 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 Daltons. The chemical structure of sunitinib malate is: Sunitinib malate is a yellow to orange powder with a pKa of 8.56.The solubility of sunitinib malate in aqueous media over the range pH 1.2 to pH 6.8 is in excess of 25 mg/mL. The log of the distribution coefficient (octanol/water) at pH 7 is 5.2. Sunitinib malate capsules, for oral use, are supplied as printed hard shell capsules containing 12.5 mg, 25 mg, 37.5 mg or 50 mg of sunitinib (equivalent to 16.7 mg, 33.4 mg, 50.1 mg, or 66.8 mg of sunitinib malate, respectively). The capsules contain the following inactive ingredients: croscarmellose sodium, mannitol, magnesium stearate and pregelatinized starch as inactive ingredients. In addition 12.5 mg capsule shell contains gelatin, titanium dioxide and red iron oxide. The white printing ink contains shellac, propylene glycol, potassium hydroxide and titanium dioxide.
