Summary
Tricyclic-type antidepressants block norepinephrine reuptake and can change adrenergic responsiveness. Isoproterenol is a direct beta agonist that is not taken up substantially by neuronal reuptake, so the effect is less predictable, but additive tachycardia and arrhythmia are possible.
What this interaction means in plain words
Amoxapine and Isoproterenol 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
Amoxapine inhibits norepinephrine reuptake and has additive cardiovascular effects with beta-adrenergic stimulation.
What to do
Monitor heart rate, blood pressure and ECG when the two are used together. Titrate isoproterenol to effect.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
