YES
This study evaluate the interindividual variabilities of plasma dispositions of tolvaptan and its metabolites determined by LC-MS/MS and clinical responses and adverse effects by investigating the patient background, plasma concentrations of proteins related with tolvaptan metabolism, and genetic variants of cytochrome P450.
PK,PD
Plasma concentrations of tolvaptan and its metabolites just before dosing on the 7th day after starting medication or later.
