Tritium-labeled quinidine (Wilzbach method), 50 mg/kg by mouth, was given to mongrel dogs. Serum, urine, bile, and myocardial radioactivity were determined simultaneously.
In six acute experiments serum levels of quinidine peaked in 2 hours, were accompanied by immediate appearance of urinary radioactivity which peaked in 1 to 2 hours and accounted for the major excretory pathway. Biliary radioactivity was somewhat delayed, reaching a peak 2 to 4 hours after administration.
Serum and myocardial levels of tritiated quinidine were correlated at 2, 4, 6, 12, and 24 hours, after a single dose of quinidine. Serum levels fell in linear fashion, being
