dc.description.abstractBackground: Many reports have shown that the efficacy of intravesical therapy for bladder cancer is in part limited by the poor penetration of drugs into the urothelium. The present study evaluated the effect of glyceryl monooleate (GMO) on the absorption of intravesically administered paclitaxel in a rabbit model of bladder cancer. Methods: Urine, plasma, and tissue pharmacokinetics were determined in rabbits treated for 120 min with paclitaxel ( 500 mu g/20 ml) by intravesical instillation. Two formulations of GMO/paclitaxel were evaluated using different proportions of water, 15 and 30%, and Taxol(R) was used as a control. Animals were observed for clinical signs of toxicity and necropsy was performed. Results: 120 min after instillation, the bladder was emptied and excised. In the urine, paclitaxel concentration was decreased by 39.6 and 41.2% in the two experimental groups and by 25.2% in the control group. The paclitaxel concentrations in the urothelium were 53 and 56% of the urine concentration in both experimental groups, but 11% in the control group. The concentration then declined exponentially in the underlying capillary-perfused tissues, reaching equilibrium at a depth of 1,400 1,700 mu m. The plasma concentrations were extremely low compared with concentrations in urine and bladder tissues and were not associated with clinical toxicity. Conclusions: We conclude that GMO has a significantly increased bioadhesiveness to bladder mucosa. Therefore, intravesical administration of GMO/ paclitaxel/ water provides a significant advantage for drugs targeting the bladder tissue, and paclitaxel represents a viable option for intravesical bladder cancer therapy.
