Stability of intravesical epirubicin infusion: a sequential temperature study

To investigate the stability of epirubicin bladder instillation, prepared from two different epirubicin formulations, under refrigerated storage, transportation and clinical use conditions.

A sequential study design was used. Epirubicin instillation (1 mg/mL) in polypropylene syringes was sequential incubated for periods of 84 days at 8 degrees C followed by 2 h at 25 degrees C and 1 h at 37 degrees C, the latter two temperatures replicating transport and intravesical conditions, respectively.

The instillation was both chemically and physically stable under those incubation conditions. The formulation of epirubicin used to prepare the instillation infusions did not affect stability.
