Summary
Tricyclic antidepressants can potentiate the cardiovascular effects of sympathomimetics such as epinephrine. Inhaled use usually results in limited systemic exposure, but increases in blood pressure, heart rate and arrhythmias are possible.
What this interaction means in plain words
Amitriptyline and Epinephrine inhaled can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Amitriptyline blocks norepinephrine reuptake and sensitizes adrenergic receptors, enhancing pressor and chronotropic responses to epinephrine.
What to do
Use the lowest effective epinephrine dose and monitor blood pressure, heart rate and rhythm. Be especially careful in patients with cardiac disease.
