“…In depressed patients activation of the thyroid axis, as indicated by increased secretion of thyroid hormones, is predictive of a rapid response to therapy with a tricyclic antidepressant (TCA) (Whybrow and Prange, 1981). Furthermore, concurrent administration of L-triiodothyronine (T 3 ) with a TCA has been found to accelerate the antidepressant effect in women Wilson et al, 1970;Wheatly, 1972;Coppen et al, 1972) and to produce a therapeutic response in patients of both sexes who previously did not respond to TCA treatment alone (Earle;1970;Hatotani et al, 1974;Ogura et al, 1974;Goodwin et al, 1982). The notion that thyroid hormones affect brain function is strengthened by evidence that in rats thyroid hormones are taken up into the synaptosomal fraction of brain neurons, and that L-thyroxine (T 4 ) is converted there to its more potent metabolite T 3 (Dratman and Crutchfield, 1978).…”

“…Tal aspecto foi abordado em apenas um estudo sobre preditores de resposta ao hormônio tireoidiano, que não encontrou diferenças entre respondedores e não-respondedores (Joffe et al, 1993). Em relação à possibilidade de interação medicamentosa, os níveis séricos dos antidepressivos tricíclicos não foram alterados pelo uso do hormônio tireoidiano (Goodwin et al, 1982;Joffe et al, 1993). A dose do hormônio utilizada foi entre 25 e 50µg/dia e não houve evidência de superioridade entre elas (Goodwin et al, 1982).…”

A dose do hormônio utilizada foi entre 25 e 50µg/dia e não houve evidência de superioridade entre elas (Goodwin et al, 1982). No entanto, foi preconizada a dose de 25µg/dia, que seria mais segura quanto aos riscos de alterações na função tireoidiana (Joffe, 1998).…”
