Abstract:
A problem to be solved by the present invention is to provide a method for ameliorating pollakiuria and nocturia, in particular, nocturia caused by nocturnal polyuria by finding a composition that enhances the antidiuretic action of vasopressin or a vasopressin V2 receptor agonist. As a result of the studies, it has been found that imidafenacin enhances the antidiuretic action of vasopressin or the vasopressin V2 receptor agonist, whereby the present invention has been completed. According to the present invention, a composition containing imidafenacin can enhance the antidiuretic action of vasopressin or the vasopressin V2 receptor agonist, making it possible to ameliorate pollakiuria and nocturia, in particular, nocturia caused by nocturnal polyuria.
