Fgfr4 inhibitor composition, preparation method therefor and pharmaceutical use thereof

Abstract

An FGFR4 inhibitor composition, a preparation method, and a pharmaceutical use are provided. The FGFR4 inhibitor composition contains a free base of the compound having formula (I) or an acid salt thereof as an active ingredient. A preparation process suitable for industrial production uses a suitable filler and other pharmaceutically acceptable carriers. A drug preparation with drug fluidity, dissolution rate, content uniformity, content of related substances, and physical and chemical stability meeting clinical requirements can be obtained, such that the requirements of clinical research and drug marketing are met, the problem of drug accessibility is solved, and the drug preparation is expected to be quickly developed into a new generation of FGFR4 inhibitors.
