F16357, a novel PAR1 antagonist improves urodynamic parameters in a rat model of Interstitial Cystitis

BACKGROUND AND PURPOSE - The aim of the present study was to characterize the role of PAR1 in rat bladder under inflammatory conditions, and determine whether a selective PAR1 antagonist, namely F16357, can prevent the pathophysiological parameters of CYP-induced IC.

EXPERIMENTAL APPROACH - Immunohistochemistry, contractile activity in isolated bladder and urodynamics were performed before and after CYP treatment. F16357 was administered intravesically during the acute phase of inflammation and effects on PAR1 receptors and PAR1-related bladder contraction were evaluated 24H after CYP injection. For telemetric experiments, urodynamics and associated voided volumes were recorded 7H and 24H after CYP. This article is protected by copyright. All rights reserved.
