THE ROLE OF PROSTANOIDS IN THE URINARY BLADDER FUNCTION AND A POTENTIAL USE OF PROSTANOID-TARGETING PHARMACOLOGICAL AGENTS IN BLADDER OVERACTIVITY TREATMENT

摘要

Overactive bladder (OAB) is a syndrome involving urinary urgency with accompanying increased daytime urinary frequency and nocturia, with or without urgency urinary incontinence, in the absence of an urinary tract infection or other obvious pathology. The detailed OAB pathophysiology remains unclear. There is evidence that OAB pathogenesis also includes abnormal bladder paracrine activity, associated with release of local prostanoids. Those agents contribute to disturbances of peripheral neuronal bladder control resulting in detrusor instability. Thus, pharmacological agents abolishing prostanoid-induced bladder overactivity seem to be a potential, future OAB therapeutical option. This paper shortly describes the rationale for nonsteroidal anti-inflammatory drugs (NSAIDs) and EP-1 receptor antagonists administration in future OAB pharmacotherapy.
