摘要:
Disclosed is a pharmaceutical composition as a tablet formulation, comprising by weight/weight percent: 25-29% of cabozantinib (N-[4-[(6,7-dimethoxy-quinolin-4-yl)oxy]phenyl]-N’-(4-fluorophenyl)-1,1-cyclopropanedicarboxamide); microcrystalline cellulose; 40-44% anhydrous lactose; 2-4% hydroxypropyl cellulose; 2-8% croscarmellose sodium; 0.1-0.4% colloidal silicon dioxide; and 0.7-0.9% magnesium stearate. Cabozantinib may be in the form of the free base, or a pharmaceutically acceptable salt such as the malate salt, and which may be in crystalline or amorphous form. Also disclosed is a process for manufacturing a pharmaceutical composition as defined above, comprising the steps of: a. delumping unmilled cabozantinib; b. premixing the delumped cabozantinib with microcrystalline cellulose, anhydrous lactose and croscarmellose sodium to form a binder solution; c. wet high shear granulation of the binder solution to produce wet granules; d. wet screening of the wet granules to produce wet screened granules; e. fluid bed drying of the wet screened granules to produce dried granules; f. dry milling of the dried granules to produce dried milled granules; g. blending the dried milled granules with colloidal silicon and croscarmellose to produce an extragranular blend; h. lubricant blending of the extragranular blend and magnesium stearate to produce a final blend; i. tablet compression of the final blend to form an uncoated core tablet; and optionally j. film coating of the uncoated core tablet, such as with a film coating composition comprising iron oxide yellow containing hypromellose, titanium dioxide, and triacetin.
