YES
This study evaluates the interindividual variabilities of plasma dispositions of tolvaptan enantiomers and their metabolites determined by LC-MS/MS and clinical responses and adverse effects by investigating the patient background, plasma concentrations of biomarkers related to tolvaptan metabolism, and genetic variants of relevant enzymes and tranporters.
PK,PD
Plasma concentrations of tolvaptan enantiomers and their metabolites just before dosing on the 7th day after starting medication or later.
