Seven healthy volunteers received a single 1.0-mg dose of intravenous digoxin in a drug-free control trial and again during concurrent therapy with therapeutic doses of quinidine. Digoxin kinetics were determined from multiple serum digoxin concentrations measured during 72 hours after dosage. Compared to the control state, quinidine coadministration reduced mean digoxin volume of distribution (15.1 vs. 12.4 l./kg), prolonged its elimination half-life (47.7 vs. 75.7 hours), and significantly reduced total clearance (6.06 vs. 2.18 ml/min.kg). Both renal and extrarenal digoxin clearances were impaired by quinidine. In nine cardiac patients receiving long-term digoxin therapy (0.25 mg twice daily), quinidine coadministration elevated mean morning digoxin levels from 1.37 to 2.0 ng/ml (P less than 0.001) and evening levels from 1.44 to 1.97 ng/ml (N.S.). If digoxin concentrations at the site of action are increased by quinidine, the interaction is likely to be of clinical importance in many patients.
