Nilotinib capsules contain nilotinib, which belongs to a pharmacologic class of drugs known as kinase inhibitors. Nilotinib drug substance, in the form of monohydrochloride monohydrate, is a white to off-white powder with the molecular formula and weight, respectively, of C 28 H 22 F 3 N 7 O•HCl • H 2 O and 584 g/mole (corresponding molecular formula and weight of nilotinib base, anhydrous are C 28 H 22 F 3 N 7 O and 529 g/mole respectively). The solubility of nilotinib in aqueous solutions decreases with increasing pH. Nilotinib is not optically active. The pK a 1 was determined to be 2.1; pK a 2 was estimated to be 5.4. The chemical name of nilotinib monohydrochloride monohydrate is 4-methyl-N-[3-(4-methyl-1H-imidazol-1-yl)-5-(trifluoromethyl)phenyl]-3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]-benzamide, monohydrochloride, monohydrate. Its structure is shown below: Nilotinib capsules, for oral use, contain 50 mg, 150 mg, or 200 mg nilotinib base, anhydrous (equivalent to 55 mg, 165 mg, and 221 mg nilotinib hydrochloride monohydrate respectively) with the following inactive ingredients: colloidal silicon dioxide, crospovidone, lactose monohydrate, magnesium stearate and poloxamer. The capsule shells contain gelatin, iron oxide red (50 mg and 150 mg), iron oxide yellow and titanium dioxide. The capsules are imprinted with edible black ink or maroon ink. The black ink is comprised of ammonium hydroxide, iron oxide black, propylene glycol and shellac. The maroon ink is comprised of ammonia solution, D&C Red #7 calcium lake, FD&C Blue #2 aluminum lake, FD&C Red # 40 aluminum lake, propylene glycol and shellac. chemical structure of nilotinib
