  • Publication number: 20240156774
    Abstract: A composition containing a docetaxel albumin nanoparticle. The composition contains docetaxel and an acid-denatured albumin, wherein the acid-denatured albumin is obtained by means of adding an acid to human serum albumin to adjust the pH value. The composition can be prepared into an injection or a freeze-dried powder injection. A composition with satisfactory physical and chemical stability is obtained by means of controlling the content of sodium octanoate in human serum albumin, preferably in an acid denaturation condition.
