Halogenated Anesthetics |
Clinical Impact: | Concomitant use may increase cardiac autonomic irritability and can sensitize the myocardium to the action of dopamine which may lead to ventricular arrhythmias and hypertension. |
Intervention: | Monitor cardiac rhythm. |
Examples: | desflurane, enflurane, isoflurane, and sevoflurane. |
MAO Inhibitors |
Clinical Impact: | Because dopamine is metabolized by monoamine oxidase (MAO), inhibition of this enzyme prolongs and potentiates the effect of dopamine which may result in severe hypertension and cardiac arrhythmia. |
Intervention: | Reduce the recommended starting dosage to no greater than one-tenth (1/10) of the recommended dose in patients who have been treated with MAO inhibitors within two to three weeks prior to the administration of Dopamine HCl in Dextrose Injection. |
Examples: | isocarboxazid, phenelzine, tranylcypromine, rasagiline, selegiline, linezolid. |
Tricyclic Antidepressants |
Clinical Impact: | Concomitant use may potentiate the cardiovascular effects of dopamine (e.g., hypertension). |
Intervention: | Monitor blood pressure. |
Examples: | amitriptyline, desipramine, doxepin, imipramine, nortriptyline. |
Vasopressors |
Clinical Impact: | Concomitant use may result in severe hypertension. |
Intervention: | Monitor blood pressure. |
Examples: | norepinephrine, epinephrine, oxytocin. |
