Resumo
Thioridazine has strong alpha-blocking and sedative activity that can produce marked additive hypotension with methyldopa. Thioridazine also carries a significant risk of QT prolongation, which adds to the concern in patients with cardiovascular disease. The interaction is mainly hemodynamic.
