Abstrakt: The effect of atenolol on the total elimination of disopyramide and its main dealkylated metabolite was studied in 6 patients and 3 volunteers. During administration of 50 mg atenolol b.i.d. the clearance of disopyramide decreased significantly ( p<0.02) from 1.90±0.71 (X±SD) to 1.59±0.68 ml/kg/min, while its half-life, concentration of the metabolite, and the volume of distribution remained unchanged. The reduction in the clearance of disopyramide by atenolol might contribute to the alleged pharmacodynamic interaction between disopyramide and β-blocking drugs. [ABSTRACT FROM AUTHOR]
