Bladder tissue permeability and transport modelling of intravesical alum, lidocaine hydrochloride, methylprednisolone hemisuccinate and mitomycin C.

The aims of this study were to assess the tissue permeability of the bladder and to characterize the transport of four drugs displaying different physico-chemical properties and commonly used in intravesical delivery, through porcine bladder. The transport of aluminium through porcine bladder was assessed by using a vertical static diffusion cell. Lidocaine hydrochloride, methylprednisolone hemisuccinate and mitomycin C were tested by using three different experimental setups, including vertical static diffusion cell, microdialyseur and lab-patented device.
