Nilotinib capsules contains nilotinib, which belongs to a pharmacologic class of drugs known as kinase inhibitors. Nilotinib drug substance, in the form of monohydrochloride sesquihydrate, is a white or slightly yellowish or slightly greenish-yellow powder with the molecular formula and weight, respectively, of C 28 H 23 ClF 3 N 7 O. 1.5 H 2 O and 593 g/mol (corresponding molecular formula and weight of nilotinib base, anhydrous are C 28 H 22 F 3 N 7 O and 529 g/mol, respectively). The solubility of nilotinib practically insoluble in water and heptane, slightly soluble in anhydrous ethanol. Nilotinib is not optically active. The pKa1 was determined to be 2.6 pKa2 was estimated to be 4.2. The chemical name of nilotinib monohydrochloride sesquihydrate is 4-methyl-N-(3-(4-methyl-1H-imidazol-l-yl)-5-(trifluoromethyl)phenyl)-3-((4-(pyridin-3-yl)pyrimidin-2-yl)amino)benzamide hydrochloride sesquihydrate. Its structure is shown below: Nilotinib capsules, for oral use, contain 50 mg, 150 mg, or 200 mg nilotinib base, anhydrous (equivalent to 56 mg, 168 mg, and 224 mg nilotinib monohydrochloride sesquihydrate respectively) with the following inactive ingredients: colloidal silicon dioxide, crospovidone, lactose monohydrate, magnesium stearate, and poloxamer 188. The capsules contain gelatin, iron oxide (red), iron oxide (yellow) and titanium dioxide. The imprinting ink contains black iron oxide, propylene glycol, potassium hydroxide and shellac. nilotinib-cap-structure
