Abstract excerpt
In patients routinely treated with metoprolol, influences of CYP2D6 genotype on the response of heart rate to isoproterenol (IP) were studied at its peak and trough concentrations and were compared with those of bisoprolol. In 72 patients treated with metoprolol or bisoprolol, CYP2D6 genotype (ie, CYP2D6*1, *2, *4, *5, *10, and *14) was determined. No patients except one who was heterozygous for CYP2D6*5 carried...
