Antagonism by tomoxetine of the depletion of norepinephrine and epinephrine in rat brain by alpha-methyl-m-tyrosine.

Tomoxetine hydrochloride, a potential antidepressant drug, antagonized the alpha-methyl-m-tyrosine-induced depletion of hypothalamic epinephrine and norepinephrine in rats. The findings suggest that tomoxetine, like several uptake-inhibiting antidepressant drugs that have been examined, inhibits uptake into epinephrine neurons as well as norepinephrine neurons in brain.
