Sex differences in the uptake and retention of imipramine and desmethylimipramine in the rat lung.

Abstract:

:14C-Imipramine was administered to male and female Sprague-Dawley rats and animals were sacrificed at 4, 8, 12, and 20 hours later. At all time points, total radioactivity in female lung was several-fold higher than in males. In addition, female lungs had a higher concentration of desmethylimipramine (DMI) as compared to imipramine than did male rat lungs. This was reflected by a higher conversion of imipramine to DMI by hepatic and pulmonary microsomes from female rats. Finally male rats cleared both imipramine and DMI from their lungs at a slower rate than did female rats.
