The invention discloses an oral
nilotinib nano-formulation which comprises an
active ingredient nilotinib, a main auxiliary material, an additional auxiliary material and a stabilizer, wherein the
mass content of the
nilotinib is 30-55%; the
mass content of the main auxiliary material is 20-40%, the
mass content of the additional auxiliary material is 2-10%, the
mass content of the stabilizer is 2-20%, and the particle size of the oral nilotinib nano-formulation is less than 1 micron. The invention further discloses a preparation method of the oral nilotinib nano-formulation. Due to the prepared oral nilotinib nano-formulation, the problems that the
medicine has low dissolubility in water and low
bioavailability in a
human body and the like are solved, the solubleness and permeability of the nilotinib are improved, and finally the aim of improving the
bioavailability is achieved. Therefore, the
digestion performance of the
medicine is greatly improved, and the
drug dissolution reaches 93-97% within 15 minutes.
