Albumin composition highly-carrying cabazitaxel medicine, preparation and preparation method thereof

The invention provides an albumin composition highly-carrying a cabazitaxel medicine, a preparation and a preparation method thereof. In the albumin composition, the medicine carrying quantity that an albumin carrier in the form of albumin nano-particles and non-nano-particles envelopes the cabazitaxel reaches 13-25 wt%, and the weight percentage content of the albumin carrier in the form of nano-particles is more than 50% of the total weight of the albumin carrier. The composition is convenient to use clinically, greatly reduces the use amount of the auxiliary material albumin, envelopes a medicine at higher efficiency and carries the medicine to a lesion, thereby achieving effects of the medicine.
