Sunitinib is a kinase inhibitor present in sunitinib malate capsules as the malate salt. Sunitinib malate is described chemically as (2 S )-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 8.95. The solubility of sunitinib malate in aqueous media over the range pH 1.2 to pH 6.8 is in excess of 0.4 mg/mL. The log of the distribution coefficient (octanol/water) at pH 7 is 5.2. Sunitinib malate capsules 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, magnesium stearate, mannitol, and povidone K-30. The 12.5 mg capsule shell contains D&C Red No. 28, FD&C Blue No. 1, FD&C Red No. 40, gelatin, and titanium dioxide. The 25 mg capsule shell contains D&C Red No. 28, FD&C Blue No. 1, FD&C Red No. 40, FD&C Yellow No. 6, gelatin, and titanium dioxide. The 37.5 mg capsule shell contains gelatin, titanium dioxide, and yellow iron oxide. The 50 mg capsule shell contains FD&C Blue No. 1, FD&C Red No. 40, FD&C Yellow No. 6, gelatin, and titanium dioxide. The black printing ink which is common for all strengths contains black iron oxide, D&C Yellow No. 10 Aluminum Lake, FD&C Blue No. 1 Aluminum Lake, FD&C Blue No. 2 Aluminum Lake, FD&C Red No. 40 Aluminum Lake, shellac, and may also contain propylene glycol. 1
