Resumo
Imipramine is a tricyclic antidepressant with quinidine-like conduction effects and QTc prolongation, and pimozide has a pronounced dose-related QTc-prolonging effect. Using them together adds to delayed repolarisation and raises the risk of torsades de pointes, especially with hypokalaemia, hypomagnesaemia, bradycardia or structural heart disease.
