摘要
Isocarboxazid irreversibly inhibits monoamine oxidase, and phenylephrine is a direct alpha-1 agonist; with MAO inhibition pressor response is potentiated because MAO inhibition reduces catecholamine breakdown and sensitises tissues. Heart-rate and blood pressure rises, arrhythmia or a hypertensive crisis can result.
