The photodegradation of doxorubicin (Dox) in the presence of hydroxypropyl‐ β ‐cyclodextrin (HP‐ β ‐CD) was studied; the degradation rate constant in the presence of HP‐ β ‐CD estimated by Lineweaver‐Burk analysis was approximately three times lower than that of free Dox aqueous solution, which shows that HP‐ β ‐CD can enhance the photostability of doxorubicin aqueous solution. The enhancement may be attributed to the inclusion interaction between HP‐ β ‐CD and doxorubicin. The characterization of FTIR, DSC, XRD and fluorescence titration indicates that 1:1 inclusion complex is formed between HP‐ β ‐CD and doxorubicin.
