Clinical Mechanism & Evidence Details
Compromised monoamine oxidase breakdown allows systemic tyramine accumulation, triggering acute hypertensive crisis.
Additive potassium retention risks hyperkalemia, which can lead to life-threatening cardiac dysrhythmias.
Inhibits intestinal CYP3A4-mediated first-pass metabolism, elevating systemic drug concentrations and increasing toxic adverse effect risks.
Alcohol may enhance gastrointestinal irritation, trigger orthostatic hypotension, or alter drug absorption kinetics.
