Propafenone disposition in renal insufficiency and renal failure.

The pharmacokinetics of a single intravenous dose of propafenone were studied in subjects with normal renal function (n = 5), renal insufficiency (n = 5), and renal failure (n = 3). No difference in central volume of distribution, total ischemic clearance or terminal half-life existed. None of the pharmacokinetic parameters examined correlated to creatinine clearance. Within the confines of the small number of patients studied, there does not appear to be any effect of renal insufficiency or failure on single-dose propafenone disposition.
