The authors have investigated the pharmacokinetics and tolerability of regadenoson, a selective A(2A) adenosine receptor agonist for use in drug-stressed myocardial perfusion imaging in subjects with varying degrees of renal function. Sixteen subjects with different creatinine clearance values (range: 15-132 mL/min) received a single intravenous bolus dose of 400 mu g regadenoson. A population pharmacokinetic model was developed to describe the pharmacokinetics of regadenoson in these subjects. Regadenoson elimination half-life was prolonged with decreasing renal function, However, maximum plasma concentrations, number, or severity of adverse events did not differ significantly between the subjects. Heart rate increased in all subjects after regadenoson injection but returned to normal within 150 minutes. There were no blood pressure pattern differences with respect to renal function. Results from this study do not indicate that dose adjustments are necessary when subjects with decreased renal function are administered the clinically relevant dose of 400 mu g regadenoson.
