In immunocytochemsitry both insulin and digoxin altered Na⁺/K⁺-ATPase α subunit immunoreactivity while their association did not. Finally, insulin increased the beating rate of neonatal rat cardiomyocytes (45±7 beats/min); so did digoxin (36±13 beats/min). The effect of insulin was prevented after pre-treated with digoxin. However, we can measure drug concentration in the blood or plasma, urine, saliva, and other easily sampled fluids (Figure 1-1).
