Stereoselective interaction of tolvaptan with amiodarone under racemic metabolic impact by CYP3A5 genotypes in heart failure patients
The diuretic effect of tolvaptan is largely blood level-dependent although it does exhibit interindividual differences according to cytochrome P450 (CYP) 3A5 genotype. This study aimed to investigate the pharm...
