Comments:
Ivermectin [3H]. Bile showed higher radioactivity levels at all times and faster depletion rate of total radioactive residue (TRR) than muscle. Highest level of residue was 3857 ng/ml d3, declined to 376 d42. Bile showed higher radioactivity at all times. radioactivity by oxidizer d1=32, d3=71, d7=72, d14=41, d28=40, d35=19, d42=16 ng/g. By LC d1=21, d3=53, d7=43, d28=22, d35=12, d42=10.
