They’re used less frequently than selective serotonin reuptake inhibitors (SSRIs) and other antidepressants because of necessary dietary precautions and risks of adverse reactions when mixed with certain drugs.
Why does tyramine cause hypertensive crisis?
In humans, if monoamine oxidase inhibitors (MAOI’s) and foods high in tyramine are ingested, tyramine is not degraded and a hypertensive crisis can result from tyramine displacing stored monoamines such as dopamine, norepinephrine, and epinephrine from synaptic vesicles.
What are Mao drugs used for?
Monoamine oxidase inhibitors (MAOIs) are an extremely strong class of antidepressants that treat depression by preventing the breakdown of the brain chemicals serotonin, dopamine, and norepinephrine. This helps them do their work of regulating your mood.
Are MAOIs safe?
They’re effective, but they’ve generally been replaced by antidepressants that are safer and cause fewer side effects. Use of MAOIs typically requires diet restrictions and avoiding certain other medications because MAOIs can cause dangerously high blood pressure when taken with certain foods or medications.
What medications should not be taken with MAOIs?
MAO inhibitors should be avoided with other antidepressants such as paroxetine fluoxetine, amitriptyline, nortriptyline, bupropion; pain medications like methadone, tramadol, and meperidine; dextromethorphan, St. Johns Wort, cyclobenzaprine, and mirtazapine.
What does tyramine do to the body?
Tyramine is a chemical in the body that helps the brain and nervous system function normally. High levels of tyramine can cause blood vessels to tighten, which increases blood pressure.
What do MAO inhibitors do?
An enzyme called monoamine oxidase is involved in removing the neurotransmitters norepinephrine, serotonin and dopamine from the brain. MAOIs prevent this from happening, which makes more of these brain chemicals available to effect changes in both cells and circuits that have been impacted by depression.
Is Prozac a MAO inhibitors?
Prozac is the brand name of the drug fluoxetine, a selective serotonin reuptake inhibitor (SSRI). SSRIs are second-generation antidepressants, which means they are newer than first-generation medications such as monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants (TCAs).
