Why does the consumption of tyramine-rich foods pose a risk for individuals taking MAOIs?
Why does the consumption of tyramine-rich foods pose a risk for individuals taking MAOIs?
- MAOIs inhibit the breakdown of tyramine, potentially leading to a buildup of tyramine and a hypertensive crisis. (correct)
- MAOIs directly convert tyramine into norepinephrine, leading to a hypertensive crisis.
- Tyramine blocks the effects of MAOIs, rendering them ineffective and causing a drop in blood pressure.
- Tyramine competes with MAOIs for enzyme binding, causing unpredictable fluctuations in mood.

Study Notes
- Buspirone is a selective 5-HT1A serotonin agonist used for Generalized Anxiety Disorder (GAD).
- Benzodiazepines like alprazolam and clonazepam are rapid-acting anxiolytics but have a high dependence/tolerance risk.
- Beta-blockers can be used for situational anxiety to block autonomic manifestations of anxiety-induced sympathetic activation (fight or flight response), such as the feeling of vomiting before an exam.
- Tricyclic antidepressants (TCAs) inhibit serotonin and norepinephrine reuptake by blocking SERT (serotonin transporter) and NET (norepinephrine transporter), allowing these neurotransmitters to stay in the synaptic cleft longer.
- Monoamine oxidase inhibitors (MAOIs) inhibit monoamine oxidase, the enzyme that breaks down dopamine, norepinephrine, and serotonin. This leads to increased levels of these neurotransmitters in the neuron and more release at the synapse.
- Imipramine equally targets SERT and NET, increasing serotonin and norepinephrine in the synaptic cleft.
- Desipramine preferentially targets NET, increasing norepinephrine.
- Clomipramine preferentially targets SERT, increasing serotonin.
- Monoamine Oxidase Inhibitors (MAOIs) are not used as frequently because they indirectly activate amines, including norepinephrine, serotonin, dopamine, and dietary tyramine.
- A buildup of tyramine can lead to excessively high levels of norepinephrine, potentially causing a hypertensive crisis.
- Modern examples of MAOIs include:
- Isocarboxazid
- Phenelzine
- Selegiline
- Clomipramine is a tricyclic antidepressant (TCA) used for obsessive-compulsive disorder (OCD).
- It targets the serotonin transporter.
- Amitriptyline is a TCA used for depression and pain management.
- Commonly used Selective Serotonin Reuptake Inhibitors (SSRIs) include:
- Escitalopram
- Fluoxetine
- Paroxetine
- Sertraline
MOA for SSRIs
- SSRIs block the serotonin transporter.
- This inhibits the reuptake of serotonin into the neuron, allowing it to stay longer in the synaptic cleft.
- This potentiates serotonin's effect on the brain/body.
- SSRIs are effective for depression, as patients with depression usually have low levels of serotonin.
MOA for SNRIs
- SNRIs block the serotonin AND norepinephrine transporter.
- This inhibits their reuptake into the neuron.
- Allows serotonin and norepinephrine to stay in the synaptic cleft longer.
- Potentiates serotonin's effect on the brain/body.
Commonly used SNRIs
- Venlafaxine
- Duloxetine
Atomoxetine
- SNRI used for ADHD
Drugs used for rapid antidepressant response
- Ketamine
- Esketamine (approved for treatment-resistant depression)
Treatment for Mania
- Carbamazepine
- Valproic Acid
- Lithium
SSRIs and SERT Blockers
- TRUE - SSRIs block the serotonin transporter (SERT)
SSRIs That Can be Used to Treat OCD
- Clorimipramine
- Fluoxetine
- Fluvoxamine
- Paroxetine
