Résumé

Tricyclic antidepressants can potentiate the pressor and arrhythmogenic effects of vasopressors by blocking norepinephrine reuptake. Dopamine acts partly indirectly, and its effect may be altered. Exaggerated hypertension or arrhythmia may occur.

Ce que signifie cette interaction, en termes simples

Amitriptyline and Dopamine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Amitriptyline belongs to Central Nervous System; Dopamine belongs to Cardiovascular.

Niveau de preuve: Moderate

Pourquoi elle survient
